ПвБПнг(А)- FRHF- (PvBPng(A)- FRHF)

SCOPE AND PURPOSE

The cables are designed for transmission and distribution of electric energy in stationary electric installations, for installation in cable structures, buildings and underground structures, including flammable and explosive areas, for supply chains of the equipment, which operates in fire.

The cables of types PvPGEng(A)-FRHF and PvBPng(A)-FRHF of rated voltage 3 kV are used in DC voltage units and they are available in single-core modification.

The class of fire hazard of the cables according to GOST 31565-2012 П1б.1.1.2.1.

STRUCTURE

Conductor

Copper, single-wire or multi-wire of the 1st or 2nd classes according to GOST 22483-2012, of the cross-section for 0.66 kV – 1.5 – 50 mm2;

for 1 kV – 1.5 – 240 mm2, single-wire – 50-630 мм2;

for 3 kV – 240 – 630 mm2.

Thermal barrier

The lapping with mica tapes.

Insulation

Cross-linked, halogen free polymer composition.

Screen for single-wire cables of nominal voltage 3kV:

It is made of copper tapes or copper wires and a copper tape overlaid spirally.

Core arrangement

Insulated conductors of multi-core cables on 0.66 and 1kV are twisted in a cable core.

The cables have got distinctive markings of insulated cores: color or digital.

Inner sheath or separating layer (for armored cables on voltage 3kV)

It is made by extrusion with filling with the halogen free polymer compositions.

Cable armoring

For cables of types PvBShvng(A)-FRHF is laid helically with two steel, galvanized tapes.

It is possible to lay the PET-tapes by winding or longitudinally over the armor.

Cable sheath or jacket

Halogen free polymer composition.
