Conductors: Flexible stranded tinned copper conductor.
Insulation: Heat resistant 3GI3 rubber based on EPR.
Outer Conductor Layer (for 3.6/6kV) : Easy strippable outer conductive layer.
Pilot Cores: Copper/steel conductor capable of expansion and compression with EPR rubber insulation.
Earth Conductor: Spiral of tinned copper wires and a conductive tape.
Inner Sheath: 2 layer design, semi conductive rubber + Rubber type 5GM5.
Armour: Spiral of steel wires, embedded in the outer sheath, fiberglas tape which prevents sheath exchanging.
Outer Sheath: Rubber type 5GM5, abrasion and tear resistant, oil resistant and flame retardant.
