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 or a constant voltage of 1 and 1.5 kV.

Cables are used for group cabling of power supply lines for electrical equipment of security systems, electrical wiring of fire safety systems, electrical wiring in hospital operating rooms, emergency power supply circuits and power equipment operating in case of fire.

Cables are also used at nuclear power plants (AS) outside the containment zone in Class 2 AS systems according to the classification of OPB 88/97 (PNAE G-01-011).

Fire hazard class of cables according to NATIONAL QUALITY STANDARD 31565 P1b.1.2.2.2
