Water Blocked P3 or P3/P10 RFOU/TFOU 6/10KV NEK606  Marine Cables

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.
