P7 or P7/P14 BFOU 6/10kV

Applications

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

Conductors : Circular tinned annealed stranded compacted copper to IEC 60228 class 2.
Conductor Screen : Semi conducting material.
Insulation : Mica tape + Halogen free EPR.
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 P7), or halogen free mud resistant thermosetting compound, SHF MUD (for TYPE P7/P14), coloured red.
