What cable is XLPE?

XLPE cable is a kind of cross-linked polyethylene cable, which plays an extremely important role in power supply network.

Basic introduction of XLPE cable

The operation of XLPE power cable lines, especially the safety and reliability of cable accessories, should be paid enough attention.    Necessary and appropriate measures must be taken to prevent accidents and monitor the operation of power cable lines.    The test scheme of XLPE cable mainly includes withstand voltage test, routine state assessment and partial discharge detection. The main cable test that can be used in field operation is partial discharge detection.    The safe operation of XLPE cables is critical to the stability of the entire power system. Once a fault occurs, it will cause a major power outage in the area under its jurisdiction.    Based on the analysis of power cable emergency repair records of major cities nationwide in 2001, photos of accident scene and fault cable sealing samples,   The causes of power cable operation failure can be divided into four types: external force damage, cable accessory manufacturing quality, cable laying and installation quality and cable body manufacturing quality,   Their respective proportions are 58%, 27%, 12% and 3% respectively. Regardless of the failure caused by external force damage, the failure of cable accessories accounts for more than 50% of the cable operation failure,   More than 97% of cable accessory faults are insulation faults, which are caused by surface discharge of solid composite dielectric. It can be seen that the operation of XLPE power cable lines,In particular, the safety and reliability of cable accessories should be paid enough attention. Necessary and appropriate measures must be taken to prevent accidents and monitor the operation of power cable lines。
