摘　　要：介绍日本开发 5 0 0 k V XL PE电力电缆时研究树枝化现象的形成 ,评述 XL PE电缆形成电树和水树与场强的相关性、树枝引发场强和长期寿命特性的研究结果 ,说明由此确定 5 0 0 k V XL PE电力电缆的绝缘设计。The research into the formation of treeing in insulation for the development of 500 kV XLPE power cable in Japan is presented. The relationship between the formatioin of water tree and electric tree and the field strength is described. The results of the study on the field strength initiated by treeing and long term characteristics are presented, upon which the insulation design of 500 kV XLPE cable is determined.
