S12 RU(c) 250 V EPR insulation, SHF2 sheathed NEK606 Instrument cable

S12 RUc 250 V

Applications : These unarmoured cables are flame retardant, low smoke and halogen free, 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 : 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.
Outer Sheath : Halogen free thermosetting compound, SHF2, coloured grey (blue for intrinsically safe).
