Description Construction

Applying area and purpose

Cables are designed for transmission and distribution of electric energy in stationary electrical installations at a rated alternating voltage of 0.66 and 1 kV with a frequency of 50 Hz

Cables are used for group cabling of power supply lines for electrical equipment of security systems, electrical wiring of fire safety systems (power supply for fire extinguishing pumps, lighting of emergency exits and escape routes, smoke extraction and ventilation systems, evacuation elevators), for wiring in operating rooms of hospitals, emergency power supply and equipment supply circuits (current collectors) functioning in case of fire. It remains operational in case of fire for 180 or 240 minutes.

Fire hazard class of cables according to NATIONAL QUALITY STANDARD 31565 P1b.1.2.2.2.2
