ПвВГЭ-ХЛ (PvVGE-KhL)

SCOPE AND PURPOSE

The cables are designed for transmission and distribution of electric energy in stationary installations on alternating voltage 0,66 and 1kV, frequency 50 Hz

The cables are used for single installation in cable constructions, open-air electrical installations (cable overpasses, arcades).

While manufacturing the cables one use the materials, which allow the cables to be resistant to low temperatures up to – 60⁰C (degrees below zero) are used.

The class of fire hazard of the cables is according to GOST 31565 01.8.2.5.4.

STRUCTURE

Conductor

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

Insulation

XLPE (color coded conductor).

Core arrangement and twisting

Insulated conductors of multi-wire conductors twisted in cable core. It is allowed to manufacture cables with SZ-stranding.

Inner sheath

PVC-compound, it is made by extrusion with filling of exterior gaps between insulated cores (for non armored and non screened cables and without SZ-stranding it is allowed manufacturing without any filling).

Screen

For cables of types PvVGE-KhL is made of copper tapes or copper wires and spiral taping with copper tape.

Taping

It is allowed to lay a separation layer of fiberglass on top of the screen in the cables with the isolation of XLPE. It is possible to lay water-blocking tape instead of the above one, that is stipulated in the order, in this case letter ‘’g’’ is entered in the designation of the cable.

Cable sheath or jacket

PVC-compound.
