Construction :

  • Conductors : Circular tinned annealed stranded copper to IEC 60228 class 2.
  • Conductor Screen : Semi conducting material.
  • Insulation : Halogen-free EPR. XLPE can be offered as an option (for TFOU cable).
  • Insulation Screen : Semi conducting material and tinned copper wire braid.
  • Bedding : Halogen free compound.
  • Armour : Tinned copper wire braid.
  • Outer Sheath : Halogen free thermosetting compound, SHF2 (for TYPE P19), or halogen free mud resistant thermosetting compound, SHF MUD (for TYPE P19/P21),coloured red.

Optional :

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