Water Blocked P2 or P2/P9 RFOU/TFOU 3.6/6KV

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 P2), or halogen free mud resistant thermosetting compound, SHF MUD (for TYPE P2/P9), coloured red.
    l???? Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
