Application

Cables with a sheath made of polyvinyl chloride plastic are intended for transmission and distribution of electric energy in stationary installations at a nominal alternating voltage of 0.66, 1, 3 and 6 kV with a nominal frequency of 50 Hz.

The cables are intended for laying single cable lines in cable structures and premises. In case of group laying, the use of fire protection equipment is mandatory. Cables can be laid without limiting the difference in levels along the laying route, including on vertical sections. Fire hazard class according to the classification of GOST 31565-2012 O 1.8.2.5.4.
