Abstract
Abstract
In this paper, the development of composite insulators at home and abroad was firstly introduced. Then several common failure forms and mechanisms of composite insulators were systematically expounded, which mainly included the failure of sheds and sheaths, brittle and decayed fracture of cores. In addition, the fracture of composite insulator cores had been the greatest threat to the safe operation of transmission lines. At last, to provide a reference for the operation and maintenance, some suggestions and measures for design, production and installation of composite insulators were put forward from practice.
