NA2XS(F)2Y

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. The cable sealing allows it to be used on the ground with high humidity and in partially submerged installations, while observing safety rules and providing protection against mechanical damage. 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 sheath that meets the conditions of fire safety). Cables can be installed without restrictions on the level difference.

Single-core XLPE insulated, aluminum conductor high voltage cable sheathed with the increased density polyethylene (PE) and a semi-conductive water-blocking tape

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 electrically 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
