| CONDUCTOR | The cable conductors can be made of copper or aluminium, depending on customer’s preference or current carrying capacity. Large size solid conductors are made of aluminium. Available constructions including: round solid conductors up to 2000mm2 (RE); circular stranded compacted conductors up to 1200mm2 (RM); circular conductors with shaped wires up to 2000mm2 (RM, Keystone conductors); segmental conductors up to 2500 mm2 (RMS, Milliken conductors); oval shaped stranded compacted conductors up to 800mm2 for external gas pressure cables (OM). |
|---|---|
| CONDUCTOR SCREEN | Extruded layer of semi-conducting cross-linkable compound is applied over the conductor and shall cover the surface completely. |
| INSULATION | Insulation is of cross-linked polyethylene compound XLPE. |
| INSULATON SCREEN | Extruded layer of semi-conducting cross-linkable compound is applied over the insulation. |
| METALLIC LAYER | The metallic layer may be applied over the core assembly collectively. The metallic screen shall consist of either copper tapes or a concentric layer of copper wires or a combination of tapes and wires. |
| SEPARATION SHEATH | Aluminum Tape sheath. |
| OUTER SHEATH | PE |
