PvVGng(A)-FRLS, PvVGEng(A)-FRLS, PvBShvng(A)-FRLS, according to specifications 16.K121-022-2011
specifications 16.K121-022-2011


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)

The overlapping with two mica tapes.



Core arrangement

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

Thermal barrier

Taped with one mica tape or one fiber glass tape.

Additional thermal barrier (for "FE 240")

Lapped with one or two mica tapes.


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

Separating layer

For cables of types PvVGEng(A)-FRLS it is made of fiber glass tape or mica tape in the form of overlapping.

Cable armoring

For cables of types PvBShvng(A)-FRLS is laid helically with two steel, galvanized tapes superimposed over thermal barrier.

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. They keep working in case of fire within 180 or 240 minutes.

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

Nominal voltage, kV 0,66 or 1
Ambient temperature during cable operation, °С from – 50 to + 50
Minimum bending radius, diameters of cable for multi-wire 7,5
for single-wire 10
The cables are laid at temperature (without preheat), °С, not below - 15
Smoke emission in the test cell not more than 50%
