General information

Standard: TŞ AZ 2002283071.008 (IEC 60840) The Russian analogue : APvKaVng 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 group cabling.

Single-core XLPE insulated, aluminum wire armored, PVC sheathed high voltage cable with a copper conductor

Structure:

  1. The conductor is copper, multi-wire, round and compacted; corresponds to class 2 of IEC 60228
  • The cross-section of a multi-wire compacted round conductor is 25÷800 mm2
  • The cross-section of a multi-wire compacted round conductor, consisting of 5 sectors, is 1000÷1600 mm2
  1. The conductor screen is made of extruded semiconducting cross-linked polyethylene
    3. Insulation is cross-linked polyethylene (2X)
    4. Insulation screen is made of extruded semiconducting cross-linked polyethylene
    5. The separation layer is made of semi-conductive water-blocking tape
    6. The screen is of copper wires fastened with copper tape (S)

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

The maximum cross-section of screen can be set based on the customer's require.

  1. The separation layer is made of PETF tape
    8. The inner sheath is made of polyvinyl chloride
    9. The armor is made of aluminum wire
    10. The outer protective sheath is made of flame retardant polyvinyl chloride (Y-fl)
