Conductor

Copper, single-wire or multi-wire core, of circular or sector-shaped form, of the 1 or 2 class according to GOST 22483.

Insulation

XLPE (color coded conductor).

Core arrangement

Insulated conductors of multi-wire cables are twisted in a cable core.

Inner sheath

It’s made with the filling of exterior gaps between the conductors of halogen-free polymer composition.

Lapping

For cables with the conductors of cross-section 50mm2 and more is made of one fiber glass tape.

Screen

For cables of types PvPEng(A)-HF the screen is made in form of lapping with copper tapes or by agreement with the customer with copper wires and a spiral taping with a copper tape.

Cable sheath

It’s made of halogen-free polymer composition.

The cables are designed for transmission and distribution of electric power in electrical networks on the alternating voltage of 1kV and frequency 50 Hz.
