CABLE CONSTRUCTION

Conductor : Annealed copper conductor, stranded according to BS EN 60228 class 2.

Insulation : Thermosetting insulation XLPE Type GP8 according to BS 7655-1.3. HEPR Type GP6 according to BS

7655-1.2 or crosslinked polyolefin material type EI 5 according to BS EN 50363-5 can be offered as option.

Inner Covering Option : The optional inner covering, where used, shall consist of an extruded layer of synthetic

polymeric material. It shall surround the single core and the laid-up two, three, four or five cores, giving the

assembly a practically circular shape.

Outer Sheath : Extruded layer of polymeric material LTS 4 according to BS 7655-6.1.

Outer Sheath Option : UV resistance, hydrocarbon resistance, oil resistance, anti-rodent and anti-termite

properties can be offered as option.
