KPSSng(A)-FRLS, KPSSGng(A)-FRLS, KPSESng(A)-FRLS, KPSESGng(A)-FRLS, according to specifications 16.K121-021-2011
specifications 16.K121-021-2011

Current-carrying conductor

Copper, single-wire of the 1 class or multi-wire not less than of the 3 class according to GOST 22483, with the cross-sections from 0.2; 0.35; 0.5; 0.75; 1; 1.5; 2.5mm2.


Silicon organic rubber (color-coded conductors).

Core arrangement and twisting

Insulated conductors are twisted in pairs.

Thermal barrier

Taped with one mica tape over each twisted pair. Twisted pairs wrapped with a mica tape are situated in parallel in the cables with two pairs.


For cables of types KPSЕSng(A)-FRLS and KPSЕSGng(A)-FRLS alum flex with a contact conductor of copper, galvanized wire is lapped over the thermal barrier in the way of winding or longitudinally by overlapping.

Over sheath

PVC-compound of low fire hazard.

The cables are designed for single or group fixed laying in fire protection systems, fire alarm systems in warning systems and evacuation management of people during fire, in buildings, constructions and structures ( industrial enterprises, schools, hospitals, office premises, high-rise buildings, subways and nuclear power plants) where requirements for cables and wires to survive in fire conditions exist.

The cables keep working in fire conditions for a period of 240 minutes.

They are operated inside and outside the premises, provided protection from direct affect of solar radiation and precipitation.

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

Nominal voltage, not more than, V 300
Ambient temperature during cable operation, °С from – 50 to + 70
Durable permissible temperature of conductors during operation, ° C + 70
The ambient temperature for laying and installation of the cables (without preheat) is made, 0C not below - 15
Minimum bending radius, diameters of the cable -with the single wire cores not less 10
-with the multi-wire cores not less 6
Fire resistance of the cables, min, not less 240
Service life, not less 15 years
Smoke generation in the test cell not more than 50%
