64/110kV XLPE Insulated, PE Sheathed High Voltage Power Cables
Application
These single core cables are designed for distribution of electrical power with nominal voltage 64/110kV. 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.
Standard
IEC 60840
Construction
|
|
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-bable compound is applied over the conductor and shall cover the surface compleby.
|
|
INSULATION
|
Insulation is of cross-bed polyethylene compound XLPE.
|
|
INSULATON SCREEN
|
Extruded layer of semi-conducting cross-bable compound is applied over the insulation.
|
|
METALLIC LAYER
|
The bllic layer may be applied over the core assembly collectively. The bllic screen shall consist of either copper tapes or a concentric layer of copper wires or a combination of tapes and wires.
