Pugs wire permissible long-term current. Pugv wire

The PV 3 (or PV-3) wire is obsolete, but still the applying designation of the BugV wire. Its characteristics and purpose are described in GOST 6323-79, adopted in the USSR. Currently, this State Standard is canceled, GOST R 53768-2010 is put into operation, but the wire itself has practically no change - except due to new technologies has become more flexible. Now he is called Pugv.

What does marking mean

Everything is simple here:

1. The first letter in the alphanumeric index is the designation of the primary type. "P" - wire.
2. The second letter indicates that the wire has insulation (as there are both "naked" wires), and denotes its type. "B" - Vinyl. Now, a polyvinyl chloride plastic with specific additives that give it additional properties is used as a dielectric envelope for this and other wires - abrasion resistance, fire resistance, an unpleasant "chemical" smell (so that the wire does not bite the mouse and rats), and the like.
3. Figure 3 means flexibility class. In total, there are (according to the old standard) of 6 flexibility classes. The greater the number, the more flexible wire. This is the difference between PV-1 and PV-3 - the first is much less flexible.

Modern abbreviation decrypt otherwise:

• PU - fixing wire;
• G - flexible;
• B - the isolation includes vinyl.

Note: Previously, the wires were divided into installation and assembly. According to modern GOST, the wire can only be installed, that is, used to connect electrical installations, but not applied in installation work.

The latter is a digit, denoting the cross section of the wire. The minimum cross section is 0.5 mm.

The installation type PV 3 may have any color, but in modern realities, it is usually produced in yellow-seen isolation. The fact is that the "earth" in various electrical installations is most often connected by this conductor. Nevertheless, the color of the shell can be any - black, gray, blue and even red.

Note: All of the above fully applies to the PV-1 wire. The whole difference between these two cables is only in flexibility - PV-1 is significantly less flexible, as it uses a multi-proper conductor with a large cross section of a single element - the wire itself.

Scope of application

The scope of PV-3, on the one hand, is quite extensive, on the other - very narrow. It is precisely the fact that it is a single wire. He can, according to GOST, used for wiring, lighting, connecting various installations inside both residential and non-residential premisesBut it is precisely the power installation that is more convenient to carry out cables with two or more by the number of conductive livers - for single-phase and three-phase connections, respectively.

Therefore, at present, one of the main tasks of PV-3 (Pugv) is a grounding connection, where a single conductor is just required. In some cases, they can be connected neutral. A beam of several wires different colors You can use instead of a shared cable where the flexibility is required primarily. It is also often used when assembling power cabinets, to connect automata, contactors and the RCD, in the industry - where single conductors are required for some reason. In this case, the connection of the wire should be carried out only using the crimping tip - pointed or in the form of a loop, since otherwise the wire is might.

It can also be used to create jumpers.

PV-3 has a voltage limit - 450 V for variable or 1000 V for DC. To connect powerful consumers, it is recommended to be applied with a loan, carefully selecting a suitable section.

When using the cable must be placed in corrugated pipe, Cable Channel or armored shell. Laying in the Earth or Witting into the wall is not allowed, since it can easily be damaged or completely converted to earth or repair and construction work. The protective shell of this type of conductors is designed for resistance to only minor mechanical effects.

Installation open way With the fixing brackets is allowed as a temporary measure, but no more.

Outdoors, including pulling method, does not apply. First, it does not apply to self-supporting, secondly, polyvinyl chloride is gradually decomposed under the action of direct sunlight.

In the presence of additional equipment The wire can be used as a TEN - for heating the frozen water pipesand the like.

Its main advantage is lightness and flexibility. The minimum bend radius is 10 outer diameters, or exactly 90 degrees.

Note: Modern Pugv has a higher class of flexibility than its ancestor PV-3 - the fifth.

This type of wire is moderately racks to fire. With single gasket, burning does not support, with a short circuit - melts, but does not spread fire. Nevertheless, it does not apply to fire-resistant wires of PV-3 and cannot be used in the zones of increased explosion and fire hazardous.

Basic TTX and Design

The PV-3 cable has the following specifications:

• building length - 100 m;
• insulation resistance - 1 MΩ;
• explorer material - copper;
• minimum temperature Gaskets - minus 15 degrees Celsius;
• range of operating temperatures - from -50 to +35 degrees;
• the maximum allowable humidity is 100% at a temperature of +35 degrees;
• standard service life - 15 years, warranty - 2 years.

Constructively, Pugv is one stranded conductor enclosed in a dielectric shell. GOST assumes that this wire can be single-core, but in practice you will not meet this, because one-core performance deprives the cable of its main advantage - flexibility. Therefore, the norm is a strainer with a number of wires of at least 7. The smaller the wire diameter, the better flexibility. So, for class 3, a copper wire is used with a diameter of up to 0.79 mm, if the total cross section does not reach 50 mm. With an increase in the diameter of the cross section, the number of wires-lived increases.

Note: When buying a PV-3 wire, it is recommended to measure the diameter D (cross section, then can be calculated by the formula S \u003d 0.785 × D²) Since many unfair manufacturers tend to save copper, understating this superworthy parameter.

The maximum diameter of the PV-3 wire can be 95 mm.

Check when buying

PV-3 cable is recommended to be very carefully checked before purchase, as the market is flooded large quantity For fakes, differing at best of the understated section, in the worst - complete inconsistency of the stated requirements, primarily on security.

1. It is always recommended to take products, in the marking of which it is worth the wording of GOST, and not that. The cable made on the th formally is not considered a fake, but the fact is that " technical conditions"Each manufacturer determines for itself.
2. A label should always be pasted on the bay, and alphanumeric marking with a certain step (about half meter) is applied to the insulation.
3. Check the cross section taken with a caliper.
4. To require the seller's documents that the wire has passed inspection to resist conductive lived, testing isolation on breakdown, tension test.

In addition, periodically during operation cable must pass "running tests".

GOST (TU / VDE) Wires Pugv:

• GOST 31947-2012 (General GOST);


• TU 16-705.501-2010 (electrocable; HCA; Belaruscabel; Energy skill; REC / PRYSMIAN; Samarakabel; auto pipe; Tollyt; Sibkabel; Rosskat; Rybinskabel; Lyubovocabel; PSKOVKABEL; ELCAL CABLE; URALACABEL; Sevkabel);


• TU 3551-009-42264279-2013 (coaxial)

Pugv The wire appeared in our market only in 2010. But this does not mean that this is the newest development and before that, this wire you could not meet in the market.

The fact is that in 2010 the new GOST R 53768-2010 entered into force. According to this regulatory document The marking of the wires has changed and the Wire of Pugv began to be called a long-proven Wire of PV - 3.

In order to deal with how the Pugv is present, let's understand the decoding of its name in detail. And then try to figure it out in the features of its design and varieties.

Decoding Marking Wire Pugv

Let's start our analysis with the decryption name. After all, no matter how it was in it, the basic wire parameters are hidden. And the understanding of this abbreviation should already give us an understanding of the design of the wire.

So:

• The first symbol we have "PU". They mean that the installation wire is installed. Previously, the wires were divided on the installation and assembly. The assembly was called less flexible wires, and the installation is more flexible. There were other differences, but these are basic. Now all the wires decided to call the installation.

• But the flexibility of the wire is still necessary to determine. Therefore, we decided to enter the symbol "g"which indicates that the wire is flexible. If this symbol is not, this means that the wire does not apply to flexible. The symbol of "g" is assigned to all wires relating to the fifth grade of flexibility in GOST22483 - 2012.
• The last characters is "in"who speaks about the type of isolation. In our case, this isolation from vinyl or how it is more correct to call polyvinyl chloride. In addition, an abbreviation may contain another letter "B". She speaks of the presence of a shell and indicates the material of this shell. But this wire is already another type.
• The last symbol that can be in the abbreviation is a fire safety indicator of the wire. Moreover, if this abbreviation is not, it means that the cable does not distribute burning during a single laying. If there is a symbol of "NG" means the wire does not distribute combustion at the group laying.

In addition, for wires with the designation "NG" GOST implies the possibility of still some characters. So "LSLTX" speaks of reduced dust and gas division during burning.

The HF symbol suggests that the cable during combustion does not emit corrosive gaseous substances. Well, the HFLTX symbol demonstrates that there is little dust, gas and corrosive substances during combustion.

After the abbreviation, figures are usually indicated. This is usually one number from 0.5 to 240. It specifies the cross section of the current part of the wire. And only in a rare case, you can meet the characters "1x1" or the like, in which the first digit indicates the number of lived, and the second cross section of the current-carrying part of the wire.

The design of the wire of Pugv

Now you can talk about the design of the wire itself. As we mentioned above the BugV wires are single-core and thanks to this, their design is quite simple.

So:

• First of all, it is a conductor who consists of several copper wires. Twisted separate wires of smaller cross-section allowed even with a large total section to ensure proper flexibility of the wire.
• The number of these individual wire depends on the cable cross section. So for wires with a cross section of 0.5 mm 2 to 35 mm 2, the minimum number of wire is 7 pieces. But usually for large diameters They are more and determined by their number of technical regulations of each individual manufacturer.
• For wires with a cross section from 50 mm 2 to 95 mm 2, the instruction involves using at least 19 wires. And for larger sections, 37 wires.
• But this is the minimum value. The actual value can be founded on the basis of the cross section of each individual wire. After all, it is quite logical here that the smaller the cross section of each individual wire, the greater their number it will be necessary in order to type the desired nominal cross-section of the wire.
• And here we come to the rescue again. So for the wire with a cross section of 0.5 mm 2, the cross section of each individual wire must be no more than 0.21 mm 2. For a wire section in 10 mm 2, this value should already be no more than 0.41 mm 2, and for the wire in 240 mm 2 will be 0.51 mm 2.

• In addition to directly the conductor, each wire necessarily has isolation. And then the same is quite logical that the larger the cross section of the wire, the thicker should be its insulation.
• And here we come to the rescue again. They normalize the nominal insulation thickness, its minimum value and maximum outdoor size Wires. You can get acquainted with these values \u200b\u200bin more detail in the photo below.

Well, to the last aspect of the constructive design of the wire can be attributed to its color. In general, this parameter is not normalized and the wire can have a solid color in any color. Only for tropical versions are not recommended to use natural colors. In the remaining cases, this aspect is negotiated with the customer.

Note! If the Wires of the Pugv are designed for use as a grounding conductor as on video, they must have a yellow-green color. In this case, any 15 cm wires should have no more than 70% of one color and at least 30 cm of the other.

Electrical and mechanical characteristics of Pugv wires

The main condition affecting the selection of wires is its characteristics. They are separated on electrical and mechanical.

Electrical characteristics of wire

Since the main purpose of the wire is the transmission of electric current, then, of course, start with electrical parameters.

And here it is important for us to the efficiency and reliability of the Pugv:

• To decide on the cost-effectiveness of the wire, we need to know its resistance. The lower this parameter, the less loss will be in the wire. But as you probably remember from the lessons of physics, the lower the temperature of the conductor, the lower its resistance. Therefore, to standardize this indicator, all calculations are made for wires with a temperature of 20⁰С.
• But there is another aspect. The higher the cross section of the wire, the less its resistance. Therefore, for each sizes of the wire, their standards are set. So the wire with a cross section of 1x6 has a resistance of 3.11 ohms per kilometer of length, and a wire of 50 mm 2-0.394 ohm / km.

• If the measured cable has a temperature different from 20 ° C, then to check the formula - R 20 \u003d R T K T 1000 / L. In this formula, R 20 is our resistance at 20 ° C, R T - the measured resistance of the core, K T is the correction coefficient that we define the table below, and L is the length of the measured area of \u200b\u200bthe wire.

• But the reliability of the Pugv wires provides high-quality isolation. To do this, conduct special high-voltage insulation tests. A voltage of 2.5 kV and the conductor must withstand them to withstand at least 5 minutes.
• In general, at a temperature of 20 ° C, the insulation of the Pugv wires should not be 5 MΩ. For installations up to 1000V, it is quite enough.
• In addition, the rules require that the insulation normally withstand and elevated temperatures. To do this, they contain data on the minimum insulation resistance at a temperature of 70 ° C. You can see these requirements in the photo below.

Mechanical characteristics of wire

But mechanical requirements for the wire are not less important. After all, it is precisely the ease of installation, the possibility of applying in many ways. different rooms, as well as in various temperature modes.

So:

• One of the most important parameters of any wire or cable is its flexibility.. It depends on how much you can bend the wire without fears to damage the conductors or isolation. Determining in this case is the bend radius.

Bending radius directly depends on the nominal wire diameter. And specifically, in our case, 5 diameters of the Pugv. This is a good enough indicator. In most less flexible products, it does not exceed 10, or even 20 diameters.

• As for aggressive environments, the wire perfectly transfers high humidity.. So at a temperature of B + 35⁰С, it can be operated in a medium with 98% humidity. And here sunlight All wires in PVC isolation are poorly transferred, and our Pugv is no exception.
• The range of operating temperatures in the Pugv is also quite high. There wire can safely work both in minus 50 ° C and at temperatures up to plus 70 ° C.

Note! If the wire installation is planning to carry out your own hands, then you must remember that the minimum temperature at which this wire can be mounted is -15⁰c. But better installation Perform with possess temperatures.

• The service life of the Pugv wires is usually 20 years. The warranty service life is usually 2 to 3 years. But considering the experience, under normal operating conditions, this brand of wire can serve you much longer.

Steps selection Wires Pugv

Interestingly, the standards provide for individual stages and for receiving the wire.

These norms are quite simple and can well be used by individuals:

	First of all, the rules recommend us to inspect the wire. It should be verified in accordance with the cross section of the wire, the correctness of its design and the absence of visible defects.
	The next step is advised to determine the electrical resistance of conductive livers. Regulatory documents require this using given and similar schemes. But in private, you can simply use an ohmmeter.
	After that, electrical tests are insulated wires. For this, the insulation resistance is measured and high-voltage tests are carried out. As we have noted above, the test voltage for the wire must be 2500V.
	All wires must have appropriate labeling. It should contain the type of wire, the sign of the manufacturer, the cross section of the vein and the year of release. In this case, this marking should be applied every 550 mm on the insulation of the wire.
	But the price of the bay of the wire should include the presence of a special label. It should be indicated by the manufacturer's factory sign, wire brand, manufacturing date, wire weight, length and conformity sign.

Output

The technical characteristics of the Pugv wires make it possible to apply it to solve a wide variety of tasks in both industry and in an individual economy. After all, the wire has very good electrical properties, excellent flexibility and an acceptable price.

For disadvantages, some refer to the fact that the wire is single-core, but in many cases it is an advantage. Therefore, if your choice fell on the Wires of the Bagv brand, then this is a good choice.

The various brands of the installation wires are used in the electrical unit of the lines of both lighting and strengths. Decoding the stamps of these cables, gives more complete information. Pugv is one of the most popular among them.

Methods of application

This is a single-core cable with an insulating material from PVC plastic, with a missing shell. The conductor is annealed twigs of copper wires (minimum of 7 pieces) of varying degrees of tinning. It is used in closed-type premises with stationary laying. Admissible use under the indoor canopy under the condition of the lack of direct sunlight. For dugV, precipitation is also unacceptable. The closed method of its laying provides for the possibility of mounting under the plaster, in brick masonry or concrete.

Decoding the abbreviation of this cable as follows:

P - denotes the wire,

Y - indicates that the wire is installed,

M - indicates that the wire is flexible,

B - denotes the insulating material from PVC plastic.

This type of cables is widely used in the arrangement of the mechanisms and machines, various electrical appliances, power cabinets to the designated alternating voltage up to 450 / 750V with a permissible frequency up to 400 Hz. Applicable use with DC voltage up to 1000 V.

According to its constructive features, technical and operational estimates, Pugv meets the conditions of international standards. Possessing a high level of flexibility, it is placed in boxes, steel pipes, trays.

With single laying, he prevents the burning. The period of its operation is the minimum of 20 years. Therefore, GOST places rather strict requirements for mechanical, electrical and structural parameters for such products. The battery life is calculated since the date of manufacture.

The size of the cross section of this wire is from 0.5 to 95 mm2. Insulating material Tightly adjacent to the conductor. It is removed without damage. Invalid cracks, foreign inclusions, dents, inhales, bubbles on isolation-changing thickness.

Wire colors

Color Gamma Pugv is diverse. The isolation color is obliged to be solid. It can also be represented by two longitudinal stripes. The strips have a natural color, are relative to each other diametrically. If the cable is used for grounding, insulation is painted in yellow-green. Zero wires are painted in blue. In general, the coloring is stipulated in advance in the order.

Our readers recommend! To save on electricity payments, our readers advise the ELECTRICITY SAVING BOX Energy Economy. Monthly payments will become 30-50% less than before the use of the economy. It removes the reactive component from the network, as a result of which the load is reduced and, as a result, consumption current. Electrical appliances consume less electricity, the costs of its payment are reduced.

If this does not happen, and there are no specific information about the color in the order, the manufacturer delivers at its discretion. Such an option is allowed when delivering products with insulation of transitional and mixed colors, with a condition of not more than 10% of the total batch.

Rules characterizing the operation of the wire

Operational characteristics of Pugv:

• You can use products in the range from -50 to + 65 ° C.
• Works on its laying are carried out at a temperature not lower than -15 ° C.
• At a temperature of no more than +35 ° C, the wire withstands the humidity of 98%.
• The radius of its bending is 5 outer diameters.
• It is distinguished by resistance to vibration, strokes, acoustic noise.
• When working, the permissible heating temperature of the conductor is up to + 70 ° C.
• The minimum construction length is 100 meters.

There is a table where the manufacturer indicates for the wire of various sections specific gravity. W. different manufacturers A permissible difference of all values \u200b\u200bby 10%.

Resistance values

There is a table of conducting resistance values \u200b\u200bdepending on its designated cross section. All resistances should not exceed the specified values. At the time of operation and storage, their increase by 20% is permissible. It should be noted that for conductors with a cross section of 0.75, 1, 1.5 mm2, electrical resistance depends on constructive features Veins.

The electrical resistance of isolation per 1 km should not be less than 1 mΩ. Before delivery, the products are checked for 5 minutes by alternating voltage of 2000 V (at a frequency of 50 Hz), immersing it into water.

During a special installation, when temperature mode -15 degrees Celsius, the Pugv must be filled with a cylinder, the diameter of which is 5 outer diameters of the wire itself. A visual example is its gasket in the refrigeration chamber.

Packing cable and its marking

The consumer gets the Pugv in the bays or wound on the drum. The minimum diameter of the device on which the cable is wound, should be no less than the value of 10 outer diameters of the cable itself. When delivered, the minimum cable length is 100 m. The presence of a twenty-meter cable in one delivery is allowed, provided that it is no more than 10% of the total.

On the insulation of the cable, relief or by punching, there is always information about its manufacturer and the Wire Designation itself. Marking must be continuous. Several labels are allowed. Maximum distance Between them - 500 mm.

The information on the label contains data on the length of the wire, the manufacturer, the date of manufacture, mass and the designation of the GOST. It is certified by a special stamp of technical control and the presence of a certification compliance mark.

Production quality verification methods

Such an inspection is carried out by visual control Products. This makes it possible to obtain a preliminary assessment of the inappropriate quality of the Pugv, if a number of measured, using tools, parameter values \u200b\u200ballows you to doubt it.

Measuring electrical resistance to the device, you need to pay special attention to a dense contact with measuring wires. If necessary, it is possible to measure a certain cable unit, followed by recalculation for a total length.

The final conclusion of quality is made after testing in a specialized laboratory.

Nevertheless, Pugv has a number of significant advantages that gives its widespread use and a guarantee of reliable operation.

The Pugv wire is a power conductor whose veins are made of copper. PVC plastic was used as an insulating composition. For this cable, the absence of a shell is characteristic. It is performed according to the standards GOST R 53768-2010. The veins are collected from tinned copper wires (rods). The number of rods is from 7 or more. Operation is carried out in closed rooms for fixed aggregates. In the absence of direct exposure to solar radiation, installation under sheds is allowed. Work is not allowed under atmospheric precipitation. With the closed laying method, you can carry out installation work under layers of plaster, in closed bricks and concrete.

Decoding

The Pugv cable is decrypted as follows:

• P - the common name of cable conductors, then the wire.
• u is an installation type product used in the electromotive of conductor lines.
• G is the flexibility index of the wire. This marking belongs to the conductors of the stranded execution as opposed to, for example, to the cords.
• B - PVC is used as insulation.

Thus, this product is a single-core conductor. Cottage elements are made of copper wires twisted with each other. The shell is absent, PVC isolation.

The numeric notation, which goes next, denote the cross-sectional area of \u200b\u200bthe wire in mm 2. For example, Pugv-4. The next letter index characterizes color marking Isolation (b - white, k - red, etc.). This condition is discussed when ordering on a product based on information on the further use of conductor products.

Features and advantages

Pugv power wire fulfills the requirements of numerous international standards on the basis of its design, technical and technological parameters. Thanks to the large flexibility of the product, it is possible to lay the wire in the box, different pipes etc.

With a single method of laying there is no risk of fire. The duration of operation is over 20 years. Duration is calculated since the production of products. In this connection, NTD has high requirements to various characteristics cable.

Information about the manufacturer, as well as the marking of the product is applied to the surface of the insulation with a stamp or relief. The designation should not be interrupted, possibly additionally a few designations, the distance between which should not exceed 500 mm. The above information includes length, manufacturer, release time, weight and GOST number. It has appropriate confirmation of technical control in the form of stamping and certifying signs.

Wire colors

Wire installation Pugv has a variety color gamut. Color coating only solid. It is possible to cover in the form of double longitudinal strips, which are arranged diametrically. Each strip has a natural color. Provided that the Pugv cable is used as a grounding, the insulating coating should be yellow-green. When used as zero wires blue colour. Color marking is discussed when ordering.

In the absence of instructions on the color designation, the manufacturer reserves the right to choose. This is possible when ordering, for example, conductors with mixed and transitional colors. However, the content of such products should be less than 10% of the summary order.

Application

This type of conductor is used to power fixed electrotechnical units in lighting networks and electrical systems. In addition, for the electromotion of various electrical devices, devices and mechanisms in closed rooms. The variable voltage value is up to 450-750 V with a frequency of up to 0.4 kHz. In networks with a constant voltage of 1 kV.

This conductor complies with the rules and norms of the following international standards for constructive and technical and technological characteristics: IEC 60227-1: 2007, IEC 60227-3: 1997, IEC 60227-4: 1997.
