КПСЭCГнг(А)-FRHF (KPSЕSGng(A)-FRHF) - Russian ana logue of JE-Li2G(St)H...Bd FE240/E90 Keram
SCOPE AND PURPOSE
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 are demanded. 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.22.214.171.124.
Copper, 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; 1.0; 1.5; 2.5 mm2.
Silicon organic rubber (color-coded conductors).
Core arrangement and twisting
Insulated conductors are twisted in pairs.
It is 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.
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.
Halogen-free polymer composition.
