General information

Standard: TŞ AZ 2002283071.008 (IEC 60840) The Russian analogue : APvKaV These cables can be used for laying on dry ground (on sandy, sandy-clay soil and soil with humidity less than 14 %), in areas with landslide and seismic activity, on frozen ground in an upright position and in areas with potential tensile force during cable operation. The cables can also be installed without restrictions for level differences. The cable does not spread combustion at a single cabling.

XLPE insulated single-conductor high-voltage cable with an aluminium conductor, with the armor of aluminium wire, and with a shell of polyvynil chloride (PVC)

Structure:

  1. The conductor is aluminium (A), multi-wire, round and compacted; corresponds to class 2 of IEC 60228
  • The section of a multi-wire compacted round conductor is 25÷1000 mm2
  • The section of a multi-wire compacted round conductor, consisting of 5 sectors is 1000÷1600 mm 2
  1. The conductor tube is made of extruded semiconducting cross-linked polyethylene
    3. Insulation is cross-linked polyethylene (2X)
    4. Insulation tube is made of extruded semiconducting cross-linked polyethylene
    5. The separation layer is made of semi-conductive water-blocking tape
    6. The tube is of copper wires fastened with copper tape (S)

Minimum tube section for cables with a conductor section of 25-120 mm2 - 16 mm2
Minimum tube section for cables with a conductor section of 150-300 mm2 - 25 mm2
Minimum tube section for cables with a conductor section of 400-1000 mm2 - 35 mm2
The minimum tube section for cables with a conductor section of 1200 mm2 and above is 50 mm2

The maximum tube section limits can be set based on the customer's require.

  1. The separation layer is made of PETF tape
    8. The inner shell is made of polyvinyl chloride
    9. The armor is made of aluminium wire
    10. The outer protective shell is made of polyvinyl chloride (Y)
