Application

VBbSHv () 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.

 

Construction

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

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

- for cables at rated voltage 6 kV – 50 MOhm.

Insulation resistance calculated for 1 km at 20 C indicated at protractedly permissible temperature for the conductors heating at operational period is at least:

  • at rated voltage 1 kV - 0.005 MOhm;
  • at rated voltage 6 kV - 0.05 MOhm.

Cables endure AC voltage test and 50 Hz frequency during 10 minutes:

  • 3.5 kV – for cables at rated voltage 1 kV;
  • 15 kV – for cables at rated voltage 6 kV.

Cables are flame retardant with a single laying.

Manufactured cable length for cables at rated voltage of 1 kV :

  • manufactured cable length must be min. 450 m for cables with main conductor cross-section 1.5-16 mm;
  • manufactured cable length must be min. 300 m for cables with main conductor cross-section 25-70 mm;
  • manufactured cable length must be min. 200 m for cables with main conductor cross-section 95-240 mm.

Manufactured cable length for cables at rated voltage of 6 kV :

  • manufactured cable length must be min. 450 m for cables with main conductor cross-section 35-70 mm;
  • manufactured cable length must be min. 400 m for cables with main conductor cross-section 92-120 mm;
  • manufactured cable length must be min. 350 m for cables with main conductor cross-section 150-240 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.

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.
