Crosslinked polyethylene is made of polyethylene by irradiation crosslinking or chemical crosslinking reaction. It has the characteristics of temperature resistance, insulation, wear resistance and good mechanical properties. It is the most widely used material in the power supply and communication cable industry. Crosslinked polyethylene can also be used in high-voltage and extra high-voltage cables due to its excellent insulation properties. In this paper, the structure characteristics and performance characteristics of crosslinked polyethylene were summarized, and the common production process of crosslinked polyethylene was compared, and the advantages of crosslinked polyethylene in the application of power supply and communication cables were further analyzed. In addition, the application status of crosslinked polyethylene in power supply and communication cables at home and abroad was summarized, the existing problems and shortcomings of the current research were put forward, and the future research direction of crosslinked polyethylene was prospected.
