This paper discusses the results of a basic study for the development of 500-kV XLPE cables. The authors have established that the factors that decide the performance of today's XLPE cables are impurities in the insulator and protrusions on the semiconductive layer, and that the insulation performance of XLPE cables is determined by the size of these defects. In model tests of XLPE cables, the minimum insulation breakdown stress of cables was determined, to set the design values for 500-kV XLPE cable. As a result, it was found that it is possible to design cable having an insulation thickness of 25 mm.
