Construction

Conductors : Circular tinned annealed stranded copper wire to IEC 60228 class 2 or class 5.

Insulation : Mica tape + Halogen free EPR compound or Mica tape + XLPE.

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.

Bedding : Halogen free compound.

Armour : Tinned copper wire braid.

Outer Sheath1 : Halogen free thermosetting compound, SHF2.

HC-fire protection : Extruded thermoplastic fire protection compound.

Taping : Lapped glass fibre tape.

Outer Sheath2: Flame retardant halogen-free thermoplastic compound, type SHF1, coloured grey (blue for intrinsically safe).
