Conductor

Copper, 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 1000mm².

Thermal barrier for CCC (current-carrying conductor) (for “FE-180” and “FE-240”)

The lapping with two mica tapes with overlapping.

Insulation

PVC-compound of low fire hazard.

Core arrangement and twisting

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

In cables of type VVG-Png(A)-FRLS the conductors are situated in parallel in one flat.

Inner sheath

PVC-compound of low fire hazard.

Thermal barrier

(For “FE-240”) is made of lapping with mica tapes.

Screen

For cables of types VVGЕng(A)-FRLS the screen is made in the form of taping with copper tapes or copper wires and a spirally imposed copper tape.

Cable armoring

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

Cable sheath or jacket

PVC-compound of low fire hazard.

The cables are designed for transmission and distribution of electric power in stationary electrical installations on the nominal alternating voltage to 0.66 and 1kV and frequency 50 Hz.

The cables are used for group installation of cable power supply lines of electrical equipment of safety systems, of the wiring circuits of the systems of fire safety( power of pumps of fire suppression. Illuminations of emergency exits and escape routes, smoke removal systems and ventilation, evacuation lifts), of the wiring in the surgical departments of hospitals, of the wiring circuits of emergency power supply of the equipment (current collectors), functioning in case of fire.

The class of fire hazard of the cables according to GOST 31565 П1б.1.2.2.2.
