1General

  • Low voltage underground cable used for underground power transmission and distribution system, rated voltage 0.6/1 kV, fixed wiring.

2Applied standard

  • TCVN 5935-1 / IEC 60502-1; TCVN 6612 / IEC 60228 or equivalent standard.

3Identification of cores

  • By color of insulation or by color stripe:
  • Single core cable: natural color of XLPE.
  • Multi-core cable: redyellowbluegreenblack or non stripe.
  • Outer sheath: black.
    Or by customer’s requirement.

4Structure

  • (1)   Conductor: By aluminum wires, concentrically stranded or compacted circular.
    (2)   Water-blocking: Without/with water-blocking material and wrapping PET tape.
    (3)   Insulation: XLPE.
    (4)   Filler and Inner sheath: PVC.
    (5)   Metallic armour: double steel tapes or double aluminum tapes.
    (6)   Outer sheath: PVC.
