ВВГЭнг(А)-FRLS (VVGЕng(A)-FRLS) – Russian analogue of NYCY, NYCWY Fire Resistance Low Smoke FE180 MICA

SCOPE AND PURPOSE

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.

The class of fire hazard of the cables according to GOST 31565 П1б.1.2.2.2.

STRUCTURE
