BFOU(c) S4 offshore communication cable Construction

Conductors: Circular tinned annealed stranded copper wire to IEC 60228 class 2.
Insulation:Mica tape + Halogen free EPR compound.
Twinning: Colour coded cores twisted together.

Collective Shielding: Pairs/triples are layed up and collectively screened by copper backed polyester tape in contact with a stranded tinned copper drain wire. Pairs/triples are numbered with numbered tape or by numbers printed directly on the insulated conductors.

Bedding:Halogen free compound.

Armour:Tinned copper wire braid.
Outer Sheath:Halogen free thermosetting compound, SHF2 (for TYPE S4). Halogen free MUD resistant thermosetting compound, SHF MUD (for TYPE S4/S8), coloured grey (blue for intrinsically safe).
