S11 RU(i) 250 V Construction

  • Conductors : Circular tinned annealed stranded copper wire to IEC 60228 class 2.
  • Insulation : 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.
  • Outer Sheath : Halogen free thermosetting compound, SHF2, coloured grey (blue for intrinsically safe).
