NYY / NYY-fl / NYY-LS

General information

Cables with rated voltages up to 0..66,; 1.0,; 3.,0 kV are used for transmission and distribution of electric energy at manufacturing entities with low and high humidity, on special cable racks, in blocks of residential buildings, in the open air, at rivers and lakes located at an altitude of up to 4,300 m above sea level. The use of these cables in trenches (under the ground) is not recommended.

STRUCTURE

  1. A twisted round or shaped electric copper or aluminum single- or multi-wire conductor
  2. PVC or SPE insulation
  3. PVC shell
