NEK606 Water Blocked Offshore & Marine Cables

Water Blocked P30 RFOU-HCF / TFOU-HCF 6/10(12) kV

Applications

• These cables are partially water blocked, fire resistant, flame retardant, low smoke and halogen free, used for emergency control, power and lighting systems that need to be operational during a 1100°C hydrocarbon fire.

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.
  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, coloured red.
  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, SHF1, coloured red.
  l??? Outer Sheath 2: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
