Abstract：Crosslinked polyethylene (XLPE) insulated cable prospects in a wide range of applications for high voltage and ultra-high voltage. The UV-initiated cross-linking technology is expected to substitute peroxide cross-linking technology and become the fundamental process of a new generation ultra-high voltage XLPE cable in the fields of high voltage power cable and submarine cable due to its simple irradiation equipment, low capital construction cost, high production efficiency and long continuous production time. In the present paper, the essential mechanism and the latest research progress of UV initiated cross-linking technology for XLPE insulating cable fabrication are systematically reviewed, investigating the kinetic and cross-linking processes in the UV-initiated photochemical reaction of polyethylene, and especially analyzing the electrical properties of UV-crosslinked polyethylene insulating materials. The analysis of UV-initiated cross-linking schemes and the prospective of UV XLPE insulation medium are also represented in high of interest, making it important significance for the development of high voltage insulation materials and new polymer synthesis technology.
