Construction
Conductors: Circular tinned annealed stranded copper to IEC 60228 class 2. Conductor Screen: Semi conducting material. Insulation: Halogen-free EPR. XLPE can be offered as an option. Insulation Screen: Semi conducting material and tinned copper wire braid. 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, coloured red. HC-fire protection: Extruded thermoplastic fire protection compound. Taping: Lapped glass fibre tape.
Outer Sheath 1: Flame retardant halogen-free thermoplastic compound, SHF1, coloured red. Outer Sheath 2: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
