Irradiation cross-linked power cable (voltage level: 0.6/1KV; execution standard: GB/T12706.1-2002)Irradiation cross-linking is poly hydrogen atom bombardment in the molecular chain of the discharge by high energy rays, so the molecular chains of voids, the adjacent molecular chains together to form CC crosslinks, formed a macromolecular network three-dimensional structure formed of crosslinked polyethylene.
The thermal properties of the irradiated XLPE can reach 105 degrees, as the irradiation crosslinking of physical crosslinking, the crosslinking water without intervention, the insulation of the water molecules in the content of not more than 100PPM, the insulation of high purity, and cable irradiation cross-linking has unique excellent characteristic in terms of electrical properties, mechanical properties, cable life 60 years up to, and the cable has the advantages of light weight, simple structure, not drop restrictions on the laying etc..

Basic structure: conductor XLPE insulated steel tape armored sheath - - - PVC sheath
Radiation crosslinked polyolefin (the main material is polyethylene) wire and cable is mainly used for heat resistant construction lines, automotive lines, aviation wire, locomotive wire and wire and motor electrical wiring, etc..
Two, medium voltage XLPE insulated power cable (voltage level: 6/6KV-26/35KV; implementation standard: GB/T12706.2-2002)
MV XLPE cables adopt polyethylene crosslinking method by full dry linear molecular structure into the space network structure using polyethylene, polyethylene converting thermoplastic for thermosetting crosslinked polyethylene, and its mechanical properties, heat aging properties and environmental stress ability have been improved to a great extent, and with electrical properties excellent. The utility model has the advantages of high normal operation temperature, simple structure, small external diameter, light weight, convenient use, no limit of laying gap, etc.. Suitable for power frequency rated voltage 1-35KV power distribution system.

Three, high voltage XLPE insulated power cable (voltage level: 64/110KV, the implementation of standards: GB/T 11017-[/B]2002; 127/220KV, 290/500KV)
XLPE cable has excellent gas performance, the dielectric loss is smaller than the paper insulation and PVC insulation, the capacitance of the XLPE cable is also small, in the absence of effective star ground system can also reduce the charging current and ground fault current. Easy installation is a big advantage compared with other XLPE cable, power cable, XLPE cable bending radius is small, light weight, terminal processing is simple, because the XLPE cable is not oily, so in the laying of lines without too much consideration, there is no more because drip oil situation can not be installed.
Excellent anti aging characteristics and strong thermal deformation of the cross-linked polyethylene cable in the normal operating temperature of 90 degrees, short-term failure of 130 degrees, and the short circuit of 250 degrees Celsius conditions can load large current.
