NA2XSY-LS cat A

General information

Standard: TŞ AZ 2002283071.008 (IEC 60840) The Russian analogue : APvVng The cable is used for fixed installation in cable lines and industrial areas. Cables can be laid on dry ground and they have no restrictions on the level difference. The cable does not spread combustion at group cabling.

High voltage cable with an aluminum conductor, with cross-linked (XLPE) insulation and PVC flame-retardant sheath with low smoke and gas emission

Structure:

  1. The conductor is aluminium (A), multi-wire, round and compacted; corresponds to class 2 of IEC 60228
  • The cross-section of a multi-wire compacted round conductor is 185÷1000 mm2
  • The cross-section of a multi-wire compacted round conductor, consisting of 5 sectors, is 1000÷1600 mm 2
  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 cross-section of 185-800 mm2 - 35 mm2
Minimum cross-section of screen for cables with a conductor cross-section of 1000 mm2 and above is 50 mm2

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

  1. Thermal barrier is made of glass or mica-containing tape; corresponds to category A according to IEC 60332
  2. The inner sheath is made of flame retardant polyvinyl chloride with low smoke and gas emission
  3. Thermal barrier is made of glass or mica-containing tape; corresponds to category A according to IEC 60332
  4. The outer protective sheath is made of flame retardant polyvinyl chloride with low smoke and gas emission (Y-LS)

Specifications:

  • Operating temperature of the conductor: +90 0C
