Single-Core <strong>Cables</strong>, with Copper Conductors, XLPE Insulated,<br />
Tape Armoured and PVC Sheathed<br />
APPLICATION<br />
Suitable for installations indoors: mostly in power supply stations and outdoors: in cable ducts, underground, and on cable<br />
trays for industries, switch-boards and power stations. Due to the good laying and mechanical characteristics, this cable<br />
is suitable when mechanical protection is required or in applications where mechanical damages are expected to occur.<br />
APPLICABLE STANDARDS<br />
medium voltage cables are designed and tested to meet or exceed the requirements of IEC 60502-2 standard.<br />
However, can also supply a range of alternative designs to meet customer-specified requirements.<br />
CABLE CONSTRUCTION<br />
Conductor<br />
Plain annealed stranded circular compacted copper conductor (Class 2).<br />
Conductor Screen<br />
Extruded layer of a cross-linkable semi-conducting compound<br />
as a stress control layer.<br />
Insulation<br />
Extruded layer of cross-linked polyethylene (XLPE).<br />
Insulation Screen<br />
Extruded layer of a cross-linkable semi-conducting<br />
compound firmly bonded to the insulation.<br />
Metallic Screen<br />
Flat plain copper tape helically applied over the insulation<br />
screen with suitable overlap.<br />
Bedding<br />
Extruded layer of Polyvinyl chloride (PVC).<br />

Tape Armouring<br />
Outer Jacket<br />
Armouring<br />
Double layer of non-magnetic (aluminum) tapes.<br />
Outer Jacket<br />
Extruded layer of Polyvinyl chloride (PVC).<br />
Note: The conductor screen, XLPE insulation and the insulation screen are extruded simultaneously in one process using triple extrusion method<br />
(Continuous Vulcanization Line). Triple extrusion method not only assures clean interfaces between the insulation and stress control layers, but also<br />
assures a construction free of Partial Discharge with high operational reliability.<br />
