CABLE CONSTRUCTION
Conductor : Annealed copper conductor, stranded according to BS EN 60228 class 2.
Fire Barrier : Mica glass tape.
Insulation : Thermosetting insulation XLPE Type GP 8 according to BS 7655-1.3. HEPR Type GP 6 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.
