Abstract :
This paper describes the development of ±250 kV DC XLPE cables. Through a series of material investigations and the evaluation of model cables using two kinds of XLPE compound containing inorganic filler to suppress the accumulation of space charge within XLPE insulation, ±250 kV DC XLPE cables and factory joints were designed and manufactured. To check the DC electrical performance and reliability of ±250 kV DC submarine cable, electrical tests, mechanical test and long-term aging tests were performed. The test results showed that they had sufficient properties and reliability for practical use
