Product Description

110kv high voltage XLPE insulated power cable have the characterstics of stable capability , advance technology , broad materials resources , low price , good flexible and easy to lay and maintain .

Conductors
The cable conductors can be made of copper or aluminium. The choice is a matter of
customer’s preference or current carrying capacity. Large size solid conductors are
made of aluminium.
Available conductor constructions:
(1)round solid conductors up to 2000 mm² (RE)
(2)circular stranded compacted conductors up to 1200 mm² (RM)
(3)circular conductors with shaped wires up to 2000 mm² (RM, Keystone conductors)
(4)segmental conductors up to 2500 mm² (RMS, Milliken conductors)
(5)oval shaped stranded compacted conductors up to 800 mm²for external gas
pressure cables (OM)
The conductors are manufactured to meet the requirements of the relevant national and
international standards. For special applications the conductors can be made watertight.
