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.

The cables are designed for use in systems of NPP of class 2 and 3 according to classification ОПБ 88/97 (ПНАЭ Г-01-011).

The climate modification B, the category of location 5, according to GOST 15150-69

The fire resistance must be not less than 180min (FE180)

Nominal voltage, kV 1
Ambient temperature during cable operation, °С from – 50 to + 50
Minimum bending radius, diameters of cable for multi-wire 7,5
for single-wire and flat 10
The cables are laid at temperature (without preheat), °С, not below - 15
Fire resistant of the cables, min, not less 180
