VVGng FRLS Power Cable 3X2.5 SQMM for russia

Specifications

     VVGng  FRLS  Power Cable   3X3.5SQMM  for russia

fire-resistant cables with copper conductors , flame retardant , low smoke and gas emission .
FR - Fire , the parameter characterizing the performance of cable products , ie, the ability of the cable to continue to perform specified functions when exposed to and after exposure to flame source for a predetermined period of time , in our case , for three or more hours .
Ng FRLS - cable fire retardant , flame retardant while installing , with low smoke and gas emission .
(a) - the index of ( a) the labeling indicates compliance with the cable category A nonproliferation burning while installing cables category ( a) are considered the safest nonproliferation burning.
The cables are designed for transmission and distribution of electricity and electrical signals in stationary electrical equipment for alternating voltages up to 1 kV to 50 Hz frequency and constant voltage 1kV .
Used for single or group laying a circuit electroreceivers fire protection systems , operational and reanimation equipment anestezionnogo hospitals and hospitals, in public places , on specific industries whose activities are connected with an open flame or high temeraturami and other equipment which should continue to operate in case of fire .
Design .
1. Conductor - copper solid or stranded, round or sector .
2 . Thermal barrier - a protective layer winding conductors of mica tapes imposed separately for each core .
3 . Insulation - flameretardant PVC . Insulated conductors of multicore cables have distinctive coloring . Neutral conductor insulation blue. Isolation of earth are bi-colored ( green and yellow ) .
4 . Inner shell - PVC , low flammability .
5 . Outer shell - from flameretardant PVC .
