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. 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. 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.
