NEK606 Water Blocked Offshore & Marine Cables

Water Blocked S15 BFOU-HCF(i) 250 V

Applications

  • These cables are fire resistant, flame retardant, low smoke and halogen free, used for emergency instrumentation, communication, control and alarm systems that need to be operational during a 1100˚C hydrocarbon fire.

Standards

  • IEC 60092-376 IEC 60092-351
    IEC 60092-359 IEC 60332-1
    IEC 60332-3-22 IEC 60754-1,2
    IEC 61034-1,2 NEK 606:2004
    IEC 60331-21 VG 95218 part 29?
Water Blocked S15 BFOU-HCF(i) 250 V

Construction

  • l???? Conductors: Circular tinned annealed stranded copper wire to IEC 60228 class 2.

    l???? Insulation: Mica tape + Halogen free EPR compound.

    l???? Twinning: Colour coded cores twisted together.

    l???? Individual Shielding: Each pairs/triples are screened by copper backed polyester tape in contact with a stranded tinned copper drain wire and wrapped with polyester tape. Pairs/triples are numbered with numbered tape or by numbers printed directly on the insulated conductors.

    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.

    l???? HC-fire protection: Extruded thermoplastic fire protection compound.

    l???? Taping: Lapped glass fibre tape.

    l???? Outer Sheath 1: Flame retardant halogen-free thermoplastic compound, type SHF1, coloured grey (blue for intrinsically safe).

    l???? Outer Sheath 2: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
