Design features of VVG 5x6

The table below shows the design features of the cable.

Core design options:

• ok - single-wire core;
• mk - multi-wire core.

Decoding of VVG and description

The first letter “B” stands for core insulation made of polyvinyl chloride. The second "B" also indicates the PVC insulation used as the overall cable sheath. The letter "G" corresponds to the designation "flexible" or "naked" because there is no armor covering over the shell. Thus, the name VVG stands for “vinyl-vinyl-naked.” The absence of any letters before the name indicates conductors made of copper.

The VVG cable uses copper conductors. The rated voltage for ordinary cables is 220/380 volts, and for power cables - 600/1000 volts. In this regard, they are widely used in various fields, including industry, everyday life, offices and other premises. Using VVG cables, industrial devices and equipment, street lighting and home electrical networks are connected. The recommended temperature when laying the wire should be at least 15C. For installation in the ground, cable ducts or PVC pipes are required to protect against mechanical damage.

The use of VVG cable is considered the safest and most profitable option. Its protection is much better than that of conventional wires. This wire is used in the construction of new houses. The cross-section for connecting sockets is 2.5 mm², and for lighting – 1.5 mm². Electric stoves are connected with a more powerful cable, at the rate of 1 mm² per 2 kW load.

The VVG cable can be two-, three-, four- or five-core. Some designs have an additional grounding and neutral conductor. Different colors make connection much easier. The neutral conductors are denoted in blue or cyan, and the grounding is yellow-green.

Application area

Cables of the VVGng brand are used for transmission and distribution of electric power with stationary installation at a rated alternating voltage of 0.66 kV and 1 kV frequency of 50 Hz.
VVGng cables are intended for use indoors, outdoors, electrical installations (ducts, pipes, trays, tunnels, etc.) in the absence of tensile loads on the cable.

VVGng cables are used in cases where increased fire safety is required to prevent the spread of combustion when laying cables in bundles. Corresponds to category A GOST 12176.

Selecting VVG cable for apartment wiring

To supply electricity to the panel at the entrance to the apartment, as a rule, a VVG 3X6 power cable is used (can also be 3X10 and 3X16). Unlike PVS and ShVVP wires, often used for installation of electrical wiring, copper cable VVG 2X4 meets higher requirements, since it is also intended for use in industry. In other words, VVG 2X4, with an equal cross-section, has a higher maximum permissible current, higher insulation quality, and supports combustion much worse. In addition, each such product undergoes production tests, which cannot be said about most of their household analogues. As for the choice of the type and cross-section of the cable for powering electrical appliances located in the apartment itself, then everything depends, first of all, on their technical characteristics. One of the most common is the VVG 2X4 brand.
