1. Irradiation crosslinked power cables (voltage level: 0.6/1KV;)

 

Irradiation cross-linked cable is using high energy X-ray bombardment poly hydrogen atoms in the molecular chain discharge, and molecular chain gaps, combined with the adjacent molecular chains together to form －C－C－ crosslinks, forming a network of molecular stereo structure and form crosslinked polyethylene.

 

The irradiated crosslinked polyethylene heat performance can reach 105 degrees, irradiation crosslinking is physical crosslink, involvement of the crosslinking without water, content of water molecules in the insulation is less than 100ppm, insulation is high purity, thus radiation cross-linking cable in the electrical properties, mechanical properties have unique excellent properties, cable life can up to 60 years. At the same time, the cable has the characteristics of light weight, simple structure, laying gap restrictions etc.

Basic structure: conductor – XLPE insulated – inner sheath – steel tape armored – PVC sheath

 

Irradiated cross linked polyolefin (main material is polyethylene) wire and cable is mainly used in heat resistant construction line, automobile line, aviation conductor, locomotive wire and electrical wiring, etc.

 

 

2, medium voltage cross linked polyethylene insulated power cables (voltage level: 6/6KV-26/35KV;)

 

Medium voltage cross-linked polyethylene cables use full dry chemical crosslinking methods using polyethylene molecules by the linear molecular structure variable space reticulated structure, so that the hot plastic polyethylene translated for thermosetting cross-linked polyethylene, the mechanical properties, heat aging properties and environmental stress on the very big degree is improved, and has excellent electrical performance. With the normal operating temperature, high temperature, simple structure, small outside diameter, light weight, easy to use, not limited by the laying gap. Suitable for power frequency rated voltage 1-35KV power distribution system.

3, high voltage cross linked polyethylene insulated power cables (voltage level: 64/110KV, 127/220KV, 290/500KV)

 

XLPE cable has excellent gas performance, dielectric loss ratio than paper insulation and PVC insulation is small, XLPE cable capacitance is small, in the absence of effective star grounding system can also reduce the charging current and grounding fault current. Easy installation is one of the major advantages of the XLPE cable, compared with other power cable, XLPE cable bending radius is small, light weight, simple processing terminal, as the XLPE cables are not oily, so in the laying don't have more consideration for line, there is no more laying due to drip oil.

4. control cable (executive standard: GB9330-88; voltage level: 450/750V)

Products adopt irradiation crosslinking polyethylene or polyvinyl chloride as the insulating layer, with excellent electrical properties, mechanical properties and chemical stability, suitable for rated voltage 0.6/1kv and below control and monitoring circuit is used for situations with protective circuit protection. The conductor of the cable is allowed to work at a temperature of 70 degrees Celsius for a long time, and the conductor of the irradiated cross-linked polyethylene cable is allowed to work at 90 degrees for a long time; the temperature of the cable is not less than 0 degrees;

 

Recommended permissible bending radius: non armoured cable should be no less than 6 times of cable shape, with armor or shield.
