General information

Standard: AZS 418-2010 (TS İEC 60502-2), TSE K 204 The Russian analogue: APvPu They are used for stationary laying in the ground and trenches, regardless of the degree of soil and water corrosiveness. It is possible to use them without protection from solar radiation in the open air, as well as in cable lines (under the condition of using a shell that meets the conditions of fire safety). Cables can be installed without restrictions on the level difference. It is allowed to install cables of this brand on complicated cable routes.

Three-core XLPE insulated, an aluminum conductor high voltage cable sheathed with increased density polyethylene (PE)

Structure:

  1. The conductor is aluminum (A), multi-wire compacted, round form, corresponds to class 2 of IEC 60228
  • The section of a multi-wire compacted round conductor is 25÷300 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: each conductor is screened with copper wire and copper tape

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

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

  1. Internal filler is polyvinyl chloride plastic
    8. The outer protective shell is made of packed polyethylene (2Yy)

Specifications:

  • Operating conductor temperature: + 90 0C
  • The maximum heating temperature of the cable conductors in case of emergency: +130 0C
  • The maximum heating temperature of the cable conductors in case of a short circuit: +250 0С
  • The duration of a short circuit (not more than): 5 seconds
  • Cable laying temperature (not less than): -20 0С
  • Ambient temperature: -60 / +50 0C
  • Minimum bending radius of the cable: 12xD (D – outer diameter of the cable)
