Conductor | Annealed copper conductor, class 5 according to BS EN 60228. |
Insulation | XLPE type GP8 according to BS 7655-1.3. |
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 | PVC Type 9 according to BS 7655-4.2. |
Outer Sheath Option | UV resistance, hydrocarbon resistance, oil resistance, anti rodent and anti termite properties can be offered as option. Compliance to fire performance standard (IEC 60332-1, IEC 60332-3, UL 1581, UL 1666 etc) depends on the oxygen index of the PVC compound and the overall cable design. LSPVC can also be provided upon request. |
