Water Blocked P7r P7/P14 BFOU 6/10kV

Construction

  • l??? Conductors: Circular tinned annealed stranded copper to IEC 60228 class 2.
    l??? Conductor Screen: Semi conducting material.
    l??? Insulation: Mica tape + Halogen free EPR.
    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 P7), or halogen free mud resistant thermosetting compound, SHF MUD (for TYPE P7/P14), coloured red.
    l??? Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
