| Abstract: | The important affairs of composite insulator string dropping in Sichuan Electric Power Corporation(SPEC)are described,the mechanism of brittle fracture of insulator rod is analyzed,and the conclusion is proposed that the acidification and brittle fracture of the early composite insulator rod are caused by water penetration due to structural defects.Furthermore,the problems existing in the composite insulators that are in operation presently in SPEC are analyzed,and the advices and suggestions are proposed f... |
