NA2XS(FL)2Yy

General information

Standard: TŞ AZ 2002283071.008 (IEC 60840) The Russian analogue : AПвПy2г These cables are used in water bodies where there is no moving water vehicles, and on the ground, without taking into account the degree of corrosiveness (in trenches or concrete channels), provided that there is protection against mechanical impact. It is allowed to install cables of this trademark on complicated cable routes.

XLPE insulated high-voltage cable with an aluminium conductor, a water-blocking semiconducting and aluminum polymer tape, and with polyethylene (PE) sheath of increased density

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 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 185-800 mm2 - 35 mm2
Minimum cross-section of screen for cables with a conductor 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. The separation layer is made of semi-conductive water-blocking tape (FL)
    8. Waterproofing tape is made of aluminum polymer tape
    9. The outer protective sheath is made of packed polyethylene (2Yy)

Specifications:
