Line post insulators: Porcelain rod post insulators are widely used in busbars and disconnecting switches in power systems.In the long run, in the process of mechanical, thermal, electrical, environmental comprehensive effect of various factors with porcelain insulator inevitably changes of various physical, chemical, causing electrical properties, mechanical strength and decline gradually with the increase of runtime ask, fever, discharge, glowing characteristics will accompany the synchronization performance degradation process.
