NEK606 Water Blocked Offshore & Marine Cables

Water Blocked P3 or P3/P10 RFOU/TFOU 6/10KV

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

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 P3), or halogen free mud resistant thermosetting compound, SHF MUD (for TYPE P3/P10), coloured red.
  l???? Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
