S16 BFOU-HCF(c) 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
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).
