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