S12 RU(c) 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
 

 

Construction :

  • 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).
