Abstract

The high-level operation and maintenance management of composite insulators is the key to the safety and reliability of transmission for overhead lines. In this paper

the basic operating conditions of the composite insulators on the transmission lines of Hunan power grid are investigated and counted

and combined with the results of the running random inspection tests over the years

the main problems are analyzed. In view of the widespread aging of composite insulator umbrella skirt silicone rubber

investigation and experimental analysis are carried out

and improvement measures and suggestions are put forward from the aspects of raw material quality supervision and new methods of aging evaluation.
