交联聚乙烯电力电缆中间头工艺改进

Improvement of Intermediate Joint Processing of Cross Linkage Polythene Electric Cables

对交联电缆热缩工艺中的应力锥进行改进，改善了电场分布，减小绝缘爬电和放电的能量，延长了中间头的使用寿命。剥切反应力锥方法较好。

This paper describes improvement of stress cone in pyrocondesation process- ing of cross linkage electric cables. The electric field distribution was improved, insulation leakage and electro-discharge energy were reduced. Therefore,service life of intermediate joints was prolonged. It is shown that gaffing anti-stress cone method is acceptable.
