S15 BFOU-HCF(i) 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.

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.
• 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).
