IEC 62067標準290/500kV XLPE 絕緣, PE護套高壓電力電纜
These single core cables are designed for distribution of electrical power with nominal voltage 290/500kV. They are suitable for installation mostly in power supply stations, indoors and in cable ducts, outdoors, underground and in water as well as for installation on cable trays for industries, switchboards and power stations.
IEC 62067
| 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 compley. |
| 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 |
