摘　　要：针对潮湿条件下长期贮存使伞裙表层受潮导致其tanδ升高的现象 ,通过多种试验证明 ,硅橡胶表层受潮不影响密封在热缩管内的PTFE绝缘 ,对复合绝缘干式高压电器的运行安全无影响。This article describes the moisturization of the superficial layer of the silicon rubber shade due to long term storage in high humidity. With various experiments, The moist superficial layer of the silicon rubber shade has no effect on the internal insulation of high voltage dry electric equipments made of synthetic materials.
