When applying belt insulation by pressing, its welding with the insulation of the cores must be excluded. On the insulation surface of the cores and the plastic shell there should be no cracks, bubbles or dents that deduce the thickness of the insulation or shell over the limit deviations.

Electrical Requirements

The electrical resistance of the conductor to direct current must comply with GOST 22483. The value of the test voltage, depending on the thickness of the insulation, must correspond to the values \u200b\u200bof the peak test voltage according to GOST 23286, increased by 2 kV.

Currently, there is a huge assortment of wires and cable products with excellent characteristics from a wide variety of manufacturers. Today in stores it is possible to purchase cable-conductor products having different designs of cores and different insulation coatings.

For the installation of modern electrics in residential premises, VVG cable is most often used, flat, with copper conductors, which meets the approved state quality standards for cable products.

Mostly standard wire cross sections are used: 1.5 mm², 2.5 mm², 4mm² and 6mm². To enter the apartment, conductors with a cross section of 10 mm² are used.

Explanation of the marking of the VVG cable.

Let's try to figure out what the marking "VVG" means, what characteristics it indicates. (This educational program was prepared by our electrician in Sergiev Posad, for which many thanks to him).

The material used for the conductive core is indicated by the letter "A" at the beginning of the marking, if it is aluminum, and remains unmarked if it is copper.

The material from which the insulating sheath of conductive conductors is made, is as follows:

"B" - polyvinyl chloride;
"P" - polymer insulation;
"Pv" is polyethylene.

Wire insulation is standardly color coded. Zero is blue, grounding is yellow-green, the remaining wire is phase.

The type of cable sheath is indicated by the letters:

"B" - polyvinyl chloride;
"Шв" - with a protective hose;
"Шп" - with a protective hose made of polyethylene;
"P" is the polymer outer.

The availability of armor is separately marked:

“B” - armored;
“G” is naked.

At the end of the marking, the form is indicated:

without designation - ordinary round;
"P" is flat.

Based on the foregoing, the VVG marking can be deciphered as follows: a copper cable, with insulation from polyvinyl chloride, with an outer sheath of polyvinyl chloride, bare (without armor), round.

VVG cable and fire safety.

VVG cables also have different fire safety labels depending on the type of vinyl insulation coating:

without designation - during a single installation it does not spread combustion, if several cables with such characteristics need to be laid nearby, additional protection against burning, for example, corrugated pipe, must be used;
"Ng" - does not support combustion, including with group;
"Ng-ls" (Low Smoke) - does not support combustion, in addition, it has reduced smoke and gas emission;
"Ng-frls" (Fire Resistance Low Smoke) - fire-resistant, does not support and does not spread combustion during group installation, while the emission of gas and smoke is reduced.

GOST or TU, or maybe fake VVG?

GOST 31996-2012 was introduced by order of Rosstandart No. 1414 dated 11/29/2012 in accordance with the decisions of the Interstate Council for Standardization, Metrology and Certification of the countries participating in the CIS and the Customs Union and has been effective since 01/01/2014.

The standard was prepared by the cover method based on the national standard GOST R 53769-2010 “Power cables with plastic insulation for a rated voltage of 0.66; 1 and 3 kV. General technical conditions ”, which in this regard was canceled from 01.01.2014. That is, it is OTU (general technical conditions).

Based on GOST 31996-2012, all manufacturers are required to develop technical specifications (technical specifications), coordinate with NIIKP (Scientific Research Institute of Cable Industry), obtain permission, a certificate for the manufacture of products and only then release the cable. That is, all cable products are manufactured on the basis of approved specifications, and the cable is marked with GOST (OTU).

Therefore, GOST marking on the cable can not be. This is one way to distinguish a fake. The exception is cable products, manufactured only by order of the Ministry of Defense of the Russian Federation. In this case, GOST 16442-80 remains valid, since there is a military addition to this standard - GOST VD 16442-80.

How to distinguish fake VVG cable?

So, a cable has many different characteristics. The most important for us will be:

the material of which the conductor itself is made;
material of which the insulation is made;
the cross-sectional area of \u200b\u200bthe wire, that is, its thickness.

The cable may not meet the standards for the composition of conductive metal. For example, the amount of copper will be underestimated, and something else will be added to compensate for the mass, and it is good if it is aluminum. It will be hard to keep up with the fantasy of unscrupulous manufacturers. Therefore, when choosing a cable, you should not consider the cheapest option, but the expensive price will not protect you from a fake. You must select cable products from trusted brands of manufacturers that you can trust.

Forging a VVG cable is scary if cheap braiding material is used. For example, it is stated that the shell is made of polyvinyl chloride, which does not support combustion. But in fact, the characteristics of the braid will not meet quality standards, the shell will burn like matches, emitting toxic smoke. From the point of view of fire safety, it is necessary to carefully approach the choice of cable.

Well, the hit of the season: the so-called truncated. Unscrupulous manufacturers mercilessly reduce the thickness of the wire, sometimes even twice. As a result, for example, the wires that go to the outlet groups with a cross-sectional area of \u200b\u200b2.5 mm², in fact, have a cross-section smaller than 1.5 mm². We observed such a fake when we were invited to diagnose a new electrician in Schelkovo in a new building. This is less than permissible for conductive wires that are designed for lighting, in other words, for light bulbs. As soon as the load from heaters, a washing machine or other powerful appliances goes along such a cable, it will burn. You understand what the consequences may be.

1. Conducting vein - copper, single-wire or multi-wire, round, first or second class according to GOST 22483.

2. Insulation - from PVC compound - PVC. The insulated conductors of multicore cables have a distinctive color. The insulation of the zero conductors is blue. The insulation of grounding conductors is carried out in two-tone green-yellow colors. Insulation thickness varies depending on cable cross-section.

4. Cable sheath - made of PVC compound, in VVGng cables made of low-flammability PVC compound.
