Research on Aging Characteristics of Operating Composite Insulator in Inner Mongolia Power Grid

Abstract

The application of composite insulators in Inner Mongolia Power Grid was introduced. A batch of composite insulators with different voltage levels, different operating years and different manufacturers were selected, and their appearance, electrical, mechanical and material properties were tested. Based on the test results, the effectiveness of each test item was obtained, the characteristics of operating composite insulator in Inner Mongolia Power Grid was analyzed, and the operation and maintenance recommendations of the composite insulator were put forward.
