摘要
用针——板电极对ＸＬＰＥ电缆绝缘的电树枝老化过程进行了实验研究，得出了ＸＬＰＥ电缆绝缘的电树起始场强值及其老化曲线，进一步证实了电树枝放电通道有丛状放电和枝状放电两种形式。丛状放电时，在一定电压范围内电压越高，丛状放电通道区域越大，老化时间越长。
The paper deals with an experiment study of electrical aging process in XLPE Insulstion with the need plane electrode. The electrical tree inception field strength and the aging curves of XLPE insulation material are presented. The experiments prove again that there are two types of discharge, they are brush type discharge and branched type discharge.
