Water Blocked P7 or P7/P14 BFOU 6/10kV

Applications

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

Standards

IEC 60092-354	IEC 60092-351
IEC 60092-359	IEC 60332-1
IEC 60331-21	IEC 60332-3-22
IEC 60754-1,2	IEC 61034-1,2
NEK 606:2004	VG 95218 part 29

Construction

Conductors: Circular tinned annealed stranded 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.
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 P7), or halogen-free mud resistant thermosetting compound, SHF MUD (for TYPE P7/P14), coloured red.
Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
