NEK606 Water Blocked Offshore & Marine Cables

Water Blocked P19 or P19/P21 RFOU 12/20KV

Applications

  • These cables are partially water blocked, flame retardant, low smoke, halogen free and mud resistant, used for fixed installation for medium voltage power.

Standards

  • IEC 60092-353 IEC 60092-351
    IEC 60092-359 IEC 60332-1
    IEC 60332-3-22 IEC 60754-1,2

Water Blocked P19 or P19/P21 RFOU 12/20KV

Construction

  • l???? Conductors: Circular tinned annealed stranded copper to IEC 60228 class 2.
    l???? Conductor Screen: Semi conducting material.
    l???? Insulation: Halogen-free EPR. XLPE can be offered as an option (for TFOU cable).
    l???? Insulation Screen: Semi conducting material and tinned copper wire braid.
    l???? Filler: Water blocking fillers, if required.
    l???? Bedding: Halogen free compound, PETP wrapping tape will be applied over the bedding, if required.
    l???? Armour: Tinned copper wire braid, PETP wrapping tape will be applied over the braiding, if required.
    l???? Water Blocking Elements: Water blocking tape and strings for providing longitudinal water tightness.
    l???? Inner Sheath: Halogen free thermosetting compound, SHF2 (for TYPE P19), or halogen free mud resistant thermosetting compound, SHF MUD (for TYPE P19/P21), coloured red.
    l???? Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.

Optional

  • P20 or P20/P22 RFOU/TFOU 18/30(36) kV.
