76/132kV XLPE Insulated, PE Sheathed High Voltage Power Cables

Application

These single core cables are designed for distribution of electrical power with nominal voltage 76/132kV. 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

76/132kV XLPE Insulated, PE Sheathed High Voltage Power Cables
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 2000mm^2 (RE); circular stranded compacted conductors up to 1200mm^2 (RM); circular conductors with shaped wires up to 2000mm^2 (RM, Keystone conductors); segmental conductors up to 2500 mm^2 (RMS, Milliken conductors); oval shaped stranded compacted conductors up to 800mm^2 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
