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

PVC-compound of low fire hazard.

Lapping

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

Over sheath

It is made by filling of outer gaps between the insulated conductors with PVC-compound of low fire hazard.

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 installation of cable inside and outside of hermetic area of nuclear power stations. The cables are designed for use in the systems of nuclear power stations of class 2 and 3 according to classification of ОПБ 88/97 (ПНАЭ Г-01-011).

The class of fire hazard of the cables according to GOST 31565 for cables П1б.1.2.2.2.

Fire resistance of the cables should be not less than 180 min (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 10
The cables are laid at temperature (without preheat), °С, not below - 15
Fire resistance of the cables, min, not less 180
Smoke emission in the test cell not more than 50%
