| Summary: | This paper introduces the development method of a light submarine cable with rated voltage of 66 kV and water tree retardant cross linked polyethylene insulation(XLPE). Through testing the breakdown performance of power frequency voltage and lightning impulse voltage on the model cable, the developed samples were tested for wet insulation quality of 500 Hz/3000 h, 50 Hz/8750 h and 50 Hz/17500 h according to CIGRE TB 722:2018. The developed products were tested for type test according to CIGRE TB 490:2012 and CIGRE TB 623:2015, and the test results fully met the requirements of the design specification. In the future, the deep sea and high-power offshore wind power interconnection array submarine cable selection, 66 kV water-tree retardant XLPE light insulated submarine cable can perfectly replace 35 kV XLPE insulated submarine cable. |
