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 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).
