General information

Standard: TŞ AZ 2002283071.008 (IEC 60840) The Russian analogue: PvVng 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.

XLPE insulated, flame retardant PVC sheathed high voltage cable with a copper conductor

Structure:

  1. The conductor is copper, multi-wire, round and compacted; corresponds to class 2 of IEC 60228
  • The cross-section of a multi-wire compacted round conductor is 185÷800 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 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

  1. The separation layer is made of PETF tape
    8. The outer protective sheath is made of flame retardant polyvinyl chloride (Y-fl)

Specifications:

  • Operating temperature of the conductor: +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 emergency: +250
  • The duration of a short circuit (not more than): 5 seconds
  • Cable laying temperature (not less than): -10 0С
  • Ambient temperature: -50 / +50 0C
  • Minimum bending radius of the cable: 15xD (D is outer diameter of the cable)
