APPLICATIONS

The S3/S7 BFOU(i) 250V cable by Bury Cable is a power and control cable specifically designed for offshore platforms, drilling vessels, and other marine facilities. In safety-critical environments, it ensures uninterrupted power and signal transmission for essential systems through outstanding fire-resistant , flame-retardant , and low-smoke zero-halogen properties, providing maximum protection for personnel and assets.

CONSTRUCTION

Electrical Characteristics

ConductorsCircular tinned annealed stranded copper wire to IEC 60228 class 2.
InsulationMica tape + Halogen free EPR compound.
TwinningColour coded cores twisted together.
Collective ShieldingPairs/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.
BeddingHalogen free compound.
ArmourTinned copper wire braid.
Outer SheathHalogen 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).
