Construction

• l???? Conductors: Circular tinned annealed stranded copper to IEC 60228 class 2.
  l???? Conductor Screen: Semi conducting material.
  l???? Insulation: Mica tape + Halogen free EPR.
  l???? Insulation Screen: Semi conducting material and tinned copper wire braid.
  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 P6), or halogen free mud resistant thermosetting compound, SHF MUD (for TYPE P6/P13), coloured red.
  l???? Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
