Application

AVVG, AVVGz (A, A) 1 kV; 6 kV

Cables are designated for power supply and distribution in fixed installations with rated AC voltage 1 kV and 6 kV at frequency 50 Hz at ambient temperature from -50 C to +50 C and relative humidity up to 98% at temperature up to 35 C, cables are intended for laying in outdoors including.

AVVGz cables are designated for fixed connection to electric devices at nominal AC voltage up to 0.66 kV at frequency 50 Hz. Cables are used for connection to devices requiring input sealing.

 

Construction

Conductors
Aluminum round single-wire or multicore conductors (class 1, 2 in accordance with GOST 22483-77).
Aluminum multicore sector-shaped conductors.

Insulation and oversheath
Insulation and oversheath are made from polyvinylchloride (PVC) compound.

Core wrapping
Polyvinylchloride (PVC) compound.

Screen for 6 kV cables
Electroconductive screen from electroconducting polyvinylchloride (PVC) compound and screen from 2 copper tapes. These tapes are gapped laid.

Minimal temperature of cable laying without pre-heating: - 15 C.

Minimum permissible bending radius of the cable at installation and routing must equal to min. 10 outer diameters of the cable for single-core cable, and min.7.5 outer diameters of the cable – for multicore cables.

Protractedly permissible temperature for the conductors heating: 70 C.

Maximum permissible temperature for the conductors heating in short circuit mode: 160 C.

Duration of short circuit mode: max. 4 seconds.

Maximum permissible temperature for the conductors heating in emergency mode: 80 C

Operation time of cables in emergency mode do not should be more than 8 hours in 24 hours, or no more than 1000 hours during all service life.

Guarantee period: 5 years from the commissioning date.

The manufacturer can ensure compliance of cable quality with requirements of current technical specification, provided all terms of transportation, storage, installation and use have been observed.

Service life: 30 years.

All products are certified.
