Conductor

Copper, single-wire, of the 1 class according to GOST 22483, with the cross-section from 0.75 to 6 mm².

Thermal barrier

The lapping with two mica tapes.

Insulation

PVC-compound of low fire hazard.

Core arrangement

From 4 to 127 insulated conductors.

The insulated conductors are twisted; there is a marker pair in each layer.

It is allowed digital and color coded marking of the conductors.

Separating layer

PVC-compound of low fire hazard.

Screen

For cables of types KVVGЕng(A)-FRLS is made in the form of taping with copper wires.

Cable armoring

For cables of types KVBbShvng(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 fixed connection to electrical devices and equipment, to assemblies of clamps of electrical switch gear with the nominal alternating voltage up to 660V of frequency up to 100 Hz or direct voltage up to 1000V, for group installation with taking into account the volume of combustible load of the cables in the fire protection systems and other systems that must remain operational in case of fire within 180 minutes.

The screened cables are used when it is necessary to protect the electrical circuits from the influence of external electric fields.

The armored cables are used in case of danger of mechanic damage in process of operation, if the cable is not exposed to significant tensile force.

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