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 to 2.5mm2.

Insulation

Silicon organic rubber (color-coded conductors).

Core arrangement and twisting

Insulated conductors are twisted in pairs. The twisted pairs are situated in parallel in cables with two pairs.

Screen

Alum flex tape with a contact conductor of copper, galvanized wire is lapped in the way of winding or longitudinally by overlapping;

-over the twisted pairs of cables KPSЕng(A)- FRHF and KPSЕGng(A)-FRHF;

- over each pair individually in two-pair cables KPSЕEng(A)-FRHF and KPSЕEGng(A)-FRHF

Over sheath

Halogen-free polymer composition.

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 in case of 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 180 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.1.1.2.1.

Nominal voltage, not more than, V 300
Ambient temperature during cable operation, °С from – 50 to + 70
Ambient temperature for laying and installation of the cables (without preheat) is made, °С, not below - 15
Minimum bending radius, diameters of the cable, *where D is a the actual outer diameter of the cable - with the single wire cores not less 10
- with the multi-wire cores not less 6
Service life, not less 15 years
Fire resistance of the cables, min, not less 180
