Conductor
Copper, single-wire or multi-wire core, of circular or sector-shaped form, of the 1 or 2 class according to GOST 22483.
Thermal barrier for CCC (current-carrying conductor)
The lapping with two mica tapes. Insulation XLPE(color coded conductor).
Core arrangement
Insulated conductors of multi-core cables are twisted in a cable core.
Inner sheath
It is made in the form of filling of outer gaps between the insulated conductors with the halogen-free polymer composition.
Taping
For cables with the cross-section 50 mm2 and more is made of mica tape or fiber glass tape.
Screen
For cables of types PvPЕng(A)-FRHF is made of lapping with copper tapes or by agreement with a customer of copper wires and a spirally imposed copper tape.
Over sheath
Of halogen-free polymer composition.
The cables are designed for transmission and distribution of electric power in networks on the nominal alternating voltage 1kV and frequency 50 Hz.
The cables are used for fixed wiring inside and outside of the hermetic area of NPP.
