ВБШвнг(А)-LS (VBShvng(A)-LS)– Russian analogue of NYBY Flame Retardant Low Smoke

SCOPE AND PURPOSE

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

The cables are used at group installations, they do not spread combustion on category A.

The cables are designed for use in cable structures and premises.

For manufacturing of the cables water blocking materials are used. They allow the cables to be resistant to longitudinal water penetration and operation of the cables in wet conditions. In that case letter ‘g’ is found in the designation of the cable. F.e. VBShvgng(A)-LS.

The class of fire hazard of the cables according to GOST 31565- 2012 П1б.8.2.2.2.

STRUCTURE

Conductor

Copper, single-wire or multi-wire core, of circular or sector-shaped form, of the 1 or 2 class according to GOST 22483.

Insulation

PVC-compound of low flammability (color coded conductor).

Core arrangement

Insulated conductors of 2, 3, 4, 5 and 6 core cables twisted in cable core.

The cables with the letter ‘g’ are twisted with the water blocking elements.

Inner sheath

PVC-compound of low flammability.

Cable armoring

For cables of type VBShvng(A)-LS is laid helically with two steel, galvanized tapes.

Cable sheath or jacket

PVC-compound of low flammability
