S15 BFOU-HCF(i) 250 V Fire Resistant Instrument cable NEK 606

S15 BFOU HCFi 250 V

Applications : These 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.
Standards : IEC 60092-376
IEC 60092-351
IEC 60092-359
IEC 60332-1
IEC 60332-3-22
IEC 60754-1,2
IEC 61034-1,2
NEK 606:2004
IEC 60331-21
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.
Individual Shielding : Each pairs/triples are screened by copper backed polyester tape in contact with a stranded tinned copper drain wire and wrapped with polyester tape. 
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).
