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.
IEC 60840
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
