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???? Filler: Water blocking fillers, if required.
  l???? 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.
  l???? Filler: Water blocking fillers, if required.
  l???? Bedding: Halogen free compound, PETP wrapping tape will be applied over the bedding, if required.
  l???? Armour: Tinned copper wire braid, PETP wrapping tape will be applied over the braiding, if required.
  l???? Water Blocking Elements: Water blocking tape and strings for providing longitudinal water tightness.
  l??? Inner Sheath: Halogen free thermosetting compound, SHF2 (for TYPE S3). Halogen free MUD resistant thermosetting compound, SHF MUD (for TYPE S3/S7), 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.
