0.66 kV and 1 kV

Cables are designated for power supply and distribution in fixed installations with rated AC voltage 1 kV and 6 kV at frequency 50 Hz at ambient temperature from -40 C to +50 C and relative humidity up to 98% at temperature up to 35 C.

 

Construction

Conductors
Copper or aluminum round single-wire or multicore conductors (class 1, 2 in accordance with GOST 22483-77).

Insulation and core wrapping
Insulation and core wrapping are made from polyvinylchloride (PVC) compound.

Oversheath
Polyvinylchloride (PVC) compound.
Oversheath is made from low risk-of-fire PVC compound for cables with «ng» designation.
Covering «BbSHv» (for cables with «BbSHv» designation)
Armour is made from 2 galvanized steel tapes and PVC compound oversheath is applied over wrapping.
