Conductor

Aluminum or copper core, single-wire or multi-wire, circular or sector-shaped form, 1 or 2 class according to GOST 22483.

Nominal cross-section area of main conductors, mm²

From 1.5 to 1000

Insulation

PVC- compound (colour coded conductor).

Stranding

Insulated conductors 2, 3, 4 and 5 core cables twisted in slotted core.

Inner sheath

Is made by extrusion with the filling exterior gaps between insulated conductors or for the unarmored cables with copper conductors by the taping with the PVC tapes, or nonwoven fabrics filling exterior gaps between insulated conductors insulating cords (bundles).

Screen

For VVGE, AVVGE is made in the form of taping with the copper tapes or by the agreement with a customer of copper wires and helically superimposed copper tape.

Cable armoring

For VBShV, AVBShV is made by taping with two steel galvanized tapes.

Oversheath or protective covering

PVC-compaund.

The cables are designed for transmission and distribution of electricity in fixed electrical installations on a nominal alternating voltage 0,66, 1 and 3 kV, frequency - 50 Hz.

Cables of types VVG, AVVG, VVGE, AVVGE, VBShV, AVBShV are designed for laying single cable lines in cable installations and premises.

Cables of types VBShV, AVBShV in a single-conductor modification is designed for use in DC voltage.

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