• AVVG, AVVGng, AVVGngd are power cables with aluminum conductors, polyvinylchloride insulation and sheath.

• They are intended for the transfer of the electric power in the stationary installations for a rated alternating voltage of 660 V and 1000 V with a frequency of 50 Hz.

• They are applied at the laying in blocks, on the specialized cable tray systems, in industrial rooms, distributive and lighting devices, and also in the usual inhabited rooms as the electric wiring. Moreover, they are widely used in dacha projects.

• It is not recommended to lay the cable in the ground, laying in the ground is allowed only with the use of mechanical protection.

AVVG Cable DETAILED DESCRIPTION

AVVG is a power cable with the aluminum conductors, PVC insulation and sheath. It is designed for transportation and distribution of the electricity in the stationary installations for a rated alternating voltage of 660 V and 1000 V with a frequency of 50 Hz.

Applicability scope

AVVG cable is one of the most well-known types of conductor. It is used for stationary single laying indoors and outdoors. AVVG is an analogue of VVG cable, while its cost is several times less than that of a copper cable with the same parameters. This makes AVVG especially popular when laying long-distance lines. And due to its light weight, AVVG can be used for the installation of electrical lines on various supports and structures.

The favorable combination of the low price and the good quality made this cable popular in the construction of residential premises, industrial facilities and the development of summer cottages. It is used for laying in blocks, on specialized cable tray systems, bridges, high mountain areas, in distribution and lighting devices, industrial premises, rooms with high humidity and fire hazard, in collectors and mines. The laying in the ground is allowed in shallow trenches using protective equipment, provided that there are no intensive mechanical loads in the form of passing vehicles and damage by the construction tools or the equipment for working on the ground.

Design

The design of AVVG is based on aluminum solid and multi wire conductors of 1st or 2d flexibility class (class 1 and 2 DSTU EN 60288). This flexibility does not allow for the use of this brand of cable in carrying and temporary wiring, which are subject to frequent bends, as this can damage or break the conductor. The conductors are covered with PVC compound and are stranded into a core in the multi conductor cables. For safety and ease of installation, the conductor insulation is color- or numerically marked. The overall coating is also made of PVC compound.

There are varieties of AVVG, which are used in places with increased requirements in the sphere of fire safety and for the group laying. These cables are marked with «ng» and «ngd». AVVGng is made in a sheath made of PVC-compound of low flammability, and AVVGngd is in a sheath that does not support combustion with reduced smoke and gas emission during a fire.
