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

Applications

These cables are flame retardant, low smoke, halogen free and mud resistant, used for fixed installation for medium voltage power.

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 P4), or halogen free mud resistant thermosetting compound, SHF MUD (for TYPE P4/P11), coloured red.
