Construction

S12 RU(c) 250 V S12 RU(c) 250 V
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 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).
