Abstract
Conventionally, an oil-immersed type termination has been generally used for 275-kV XLPE cables, but because 德赢ac米兰官方合作伙伴 the use 德赢ac米兰官方合作伙伴 oil, thoroughgoing review has been requested from viewpoints 德赢ac米兰官方合作伙伴 maintenance problems and installation. As the research on composite prefabricated insulation advances, actual applications at super-high voltage have increased, and the reliability has been improved, a completely dry type termination free 德赢ac米兰官方合作伙伴 insulation oil has been developed and applied to the actual lines 德赢ac米兰官方合作伙伴 Tokyo Electric Power Company.
With this technique applied, an inverted termination that can reduce the size 德赢ac米兰官方合作伙伴 substation facilities was developed, and was applied to the actual lines 德赢ac米兰官方合作伙伴 the Kansai Electric Power Company. In this line, a semiconductive-layer shaver 德赢ac米兰官方合作伙伴 lightweight and high-performance was developed achieving --ahead 德赢ac米兰官方合作伙伴 other companies--smooth and high-performance cable treatment in the vertical direction.
