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 P7), or halogen free mud resistant thermosetting compound, SHF MUD (for TYPE P7/P14), coloured red.
l Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
