摘　　要：通过对±500kV葛南线防污改造中存在的不足,提出“倒V串”防污改造技术。针对线路的实际情况,对采用“倒V串”的结构布置、受力特征、金具研制等方面进行分析,并在葛南线中挂网运行,取得良好的效果。In the light of the shortcoming of the previous modificationinsulators of±500kV Ge-nan transmission line, the innovation techniqueon the anti-contamination of for the anti-contamination of insulator string in “∧”shape was raised. In connection with the practical circumstance, the arrangement and stress of insulator string in “∧”shape and the development of the metal ware were analyzed.This innovation technique had been applied in Ge-nan transmission line and had yielded a good result.
