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.
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.
Bedding: Halogen free compound, PETP wrapping tape will be applied over the bedding, if required.
Armour: Tinned copper wire braid, PETP wrapping tape will be applied over the braiding, if required.
Water Blocking Elements: Water blocking tape and strings for providing longitudinal water tightness.
Inner Sheath: Halogen free thermosetting compound, SHF2.
HC-fire protection: Extruded thermoplastic fire protection compound.
Taping: Lapped glass fibre tape.
Outer Sheath 1: Flame retardant halogen-free thermoplastic compound, type SHF1, coloured grey (blue for intrinsically safe).
Outer Sheath 2: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
