IEC 60092-376 IEC 60092-351 IEC 60092-359 IEC 60332-1 IEC 60332-3-22 IEC 60754-1,2 IEC 61034-1,2 NEK 606:2004 IEC 60331-21 VG 95218 part 29
Construction
-
l Conductors: Circular tinned annealed stranded copper wire to IEC 60228 class 2.
l Insulation: Mica tape + Halogen free EPR compound.
l Twinning: Colour coded cores twisted together.
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 Filler: Water blocking fillers, if required.
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.
