Construction

• l    Conductors: Circular tinned annealed stranded copper wire to IEC 60228 class 2.
  l    Insulation: Halogen free EPR compound.
  l    Twinning: Colour coded cores twisted together.
  l    Filler: Water blocking fillers, if required.
  l    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.
  l    Water Blocking Elements: Water blocking tape and strings for providing longitudinal water tightness.
  l    Inner Sheath: Halogen free thermosetting compound, SHF2, coloured grey (blue for intrinsically safe).
  l    Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
