HOMEPRODUCTS MARINE CABLES

 

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

 

Applications :

Marine 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 60092-360

IEC 60332-1

IEC 60331-21

IEC 60332-3-22

IEC 60754-1,2

IEC 61034-1,2

NEK 606

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.
