Construction :
• The phase conductor is concentrically stranded, compressed soft copper or 1350-H16/26 aluminum alloy
• Cable is composed of the conductor with moisture block in the strands, covered by a semi-conducting cross-linked polyethylene strand shield, a tree-retardant cross-linked polyethylene primary insulation, and a semi-conducting cross-linked polyethylene insulation shield
• Conductors are available with either 100% or 133% insulation levels
• Concentric neutral of bare copper wires and an insulating polyethylene jacket is applied over the insulation shield
• Cable identified by surface print on the jacket and with the lightning bolt symbol for supply cables indented in the jacket
