POWER CABLES FIRE-RESISTANT, FLAME RETARDANT AT GROUP INSTALLATION, WHICH DO NOT EMMIT TOXIC CORROSIVE ACTIV GASEOUS PRODUCTS WHILE BURNING AND SMOULDERING (modification «flame retardant – Fire-Resistant Halogen-Free»)

SCOPE AND PURPOSE

The cables are designed for transmission and distribution of electric power and electric signals in stationary electric units on the nominal alternating voltage 0,66 and 1kV and frequency up to 100 Hz.

The cables are used for group installation of cable power lines of safety systems, wiring circuits of fire safety, wiring circuits of the surgical departments of hospitals, circuits of emergency electric power of equipment, functioning in case of fire, in the absence of danger of mechanical damage during operation.

The cable is manufactured for general application and application at nuclear power plants (NPP) outside the hermetic area in the systems NPP of class 2 according to classification НП-001–2015.

The class of fire hazard of the cables according to GOST 31565 П1 б.1.1.2.1.
