 Water Blocked P4 or P4/P11 RFOU/TFOU 8.7/15KV

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.

Filler: Water blocking fillers, if required.

Bedding: Halogen free compound, PETP wrapping tape will be applied over the bedding, if required.

Armour: Tinned copper wire braid, PETP wrapping tape will be applied over the braiding, if required.

Water Blocking Elements: Water blocking tape and strings for providing longitudinal water tightness.

Inner Sheath: Halogen free thermosetting compound, SHF2 (for TYPE P4), or halogen free mud resistant

thermosetting compound, SHF MUD (for TYPE P4/P11), coloured red.

Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low

smoke standard.
