S4 or S4/S8 BFOU(c) 250V Armour& Collective Shielding fire resistant NEK606 Instrumentation cable

S4 or S4S8 BFOUc 250V

Applications : These cables are fire resistant, flame retardant, low smoke, halogen free and mud resistant, used for instrumentation, communication, control and alarm systems.
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
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.
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 Sheath : Halogen free thermosetting compound, SHF2 (for TYPE S4). Halogen free MUD resistant thermosetting compound, SHF MUD (for TYPE S4/S8), coloured grey (blue for intrinsically safe).
