How To Operate And Maintain Insulators

The overhead power line insulators tester can help many power workers to conduct various power tests more conveniently.

Composite tension insulator has been widely used in power systems due to its many advantages such as light weight, high strength, strong pollution flash resistance, and convenient manufacturing and maintenance, breaking the long-term dominance of porcelain and glass insulators. According to incomplete statistics, the total number of composite insulators in operation in my country's power grid is about 2 million. In terms of the number of uses, my country has become the second largest country in the use of composite insulators after the United States. However, with the increase in operating time and number of operations, the information on composite insulator failures has gradually increased. According to incomplete statistics, as of 1998, 15 interface breakdown accidents occurred in East China and North China, and 23 pollution flash accidents occurred in Guangdong, East China, and North China. Obviously, while improving the formula and manufacturing process and improving the quality of composite insulators, it is of great significance to carry out targeted research on operating composite insulator detection technology to ensure the safe operation of the power grid.
