General information

Standard: AZS 418-2010 (TS İEC 60502-2), TSE K 204 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. Cables can also be installed without restrictions on level differences. The cable does not spread combustion in case of group cabling.

Single-core XLPE insulated, aluminum wire armored, flame retardant PVC sheathed high voltage cable with an aluminum conductor

Structure:

  1. The conductor is aluminum (A), multi-wire compacted, round form, corresponds to class 2 of IEC 60228
  • The cross-section of a multi-wire compacted round conductor is 25÷1000 mm2
  • The cross-section of a multi-wire compacted round conductor, consisting of 5 sectors, is 1000÷1600 mm2
  1. The outer 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 of copper wires fastened with copper tape (S)

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

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