ZMS 케이블 저전압 4*240mm2 알루미늄 코어 XLPE 절연 PVC 피복 전원 케이블

APPLICATIONS of xlpe cable

These single core XLPE cables are designed for distribution of electrical power with nominal voltage 290/500kV. 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 of high voltage cable

IEC 62067

CONSTRUCTION of  xlpe cable

Conductor of 500kv xlpe cable

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 of xlpe cable

Extruded layer of semi-conducting cross-linkable compound is applied over the conductor and shall cover the surface completely. 

Insulation  of xlpe cable

Insulation is of cross-linked polyethylene compound XLPE.
Insulaton Screen  of 500kv xlpe cable

Extruded layer of semi-conducting cross-linkable compound is applied over the insulation.

Metallic Layer  of 500kv cable

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.
