Construction
Conductors: Circular tinned annealed stranded copper wire to IEC 60228 class 2.
Insulation: Mica tape + Halogen-free EPR compound.
Twinning: Colour-coded cores twisted together.
Filler: Water blocking fillers, if required.
Individual Shielding: Each pair/triple 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.
Filler: Water blocking fillers, if required.
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.
