Armoured aluminum power cables with PVC insulation 0.66 kV

Armoured aluminum power cables with PVC insulation

GOST 16442-80
IEC 60502-1 (1998-11)

 

Application

AVBbSHv (A) 0.66 kV

Cables are designated for power supply and distribution in fixed installations with rated AC voltage 0.66 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.

 

Construction

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

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

Covering «BbSHv» (in accordance with GOST 7006-72)
Armour is made from 2 galvanized steel tapes and PVC compound oversheath is applied over wrapping.

Technical characteristics

AVBbSHv 2, 3, 4 4.0 — 50

Electric resistance of conductors to DC complies with GOST 22483.

Insulation resistance calculated for 1 km at temperature 20 C:

Nominal conductor cross-section, mm Insulation resistance, MOhm, no less
2.5 — 4 10
6 9
10 — 50 7

Insulation resistance calculated for 1 km at temperature 20 C indicated at protractedly permissible temperature for the conductors heating at operational period at least 0.005 MOhm.

Cables endure AC 3.0 kV test and 50 Hz frequency during 10 minutes.

Cables are flame retardant with a single laying.

Manufactured cable length:

  • manufactured cable length must be min. 450 m for cables with main conductor cross-section 2.5-16 mm;
  • manufactured cable length must be min. 300 m for cables with main conductor cross-section 25-50 mm.

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.

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.
