S16 BFOU-HCF(c) 250 V

Applications

Caledonian NEK606 standard S16 BFOU-HCF(c) 250 V cables are fire resistant, flame retardant, low smoke and halogen free, used for emergency instrumentation, communication, control and alarm systems that need to be operational during a 1100??hydrocarbon fire.

Construction

Conductors	Circular tinned 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 Sheath1	Halogen free thermosetting compound, SHF2.
HC-fire protection	Extruded thermoplastic fire protection compound.
Taping	Lapped glass fibre tape.
Outer Sheath2	Flame retardant halogen-free thermoplastic compound, type SHF1, coloured grey (blue for intrinsically safe).
