BFOU(i) S3/S7 flame retardant offshore communication cable construction

1.Conductors: Circular tinned annealed stranded copper wire to IEC 60228 class 2.
2.Insulation: Halogen free EPR compound.
3.Twinning: Colour coded cores twisted together.
4.Individual Shielding: Each pairs/triples are screened by copper backed polyester
5.tape in contact with a stranded tinned copper drain wire and wrapped with polyester
6.tape. Pairs/triples are numbered with numbered tape or by numbers printed directly on the insulated conductors.
7.Bedding: Halogen free compound.
8.Armour: Tinned copper wire braid.
9.Outer Sheath: Halogen free thermosetting compound, SHF2 (for TYPE S3). Halogen free MUD resistant thermosetting compound, SHF MUD (for TYPE S3/S7), coloured grey (blue for intrinsically safe).
