Conductor

Copper or aluminum single-wire or multi-wire core, of circular or sector-shaped form, of the 1 or 2 class according to GOST 22483 with the cross-section from 1.5 to 1000 mm2

Insulation

PVC-compound (color coded conductor).

Core arrangement

Insulated conductors of 2, 3, 4 and 5 core cables twisted in cable core.

Inner sheath

It is made by filling of exterior gaps between cores with the PVC-compound of low flammability.

Screen

For VVGEng(A) and AVVGEng(A) is made in the form of taping with the copper tapes or by the agreement with a customer of copper wires and helically superimposed copper tape.

Cable armoring

For cables of types VBShvng(A) and AVBShvng(A) cable armor is laid helically with two steel, galvanized tapes.

Cable sheath or jacket

PVC-compound of low flammability

The cables are designed for transmission and distribution of electric energy in stationary installations on alternating voltage 0,66; 1 and 3 kV, frequency 50 Hz

The cables of types VVGng(A), AVVGng(A), VVGEng(A), AVVGEng(A), VBShvng(A), AVBShvng(A) are used for group installation in cable lines and cable constructions and open-air electrical installations (cable overpasses, arcades).

The single-wire cables of types VBShvng(A) and AVBShvng(A) are used for operations in networks of DC voltage.

The class of fire hazard of the cables is according to GOST 31565 Ï1á.8.2.5.4.

Nominal voltage, kV 0,66 or 1 or 3
Ambient temperature during cable operation, °С from – 50 to + 50
Minimum bending radius, diameters of cable for multi-core 7,5
for single-core 10
The cables are laid at temperature (without preheat), 0C not below - 15
