Research and Application on Polymer Composite Insulator of Locomotive Roof

The polymer composite insulator had been used to increase g9 led flashover gradient in order to solve the phenomenon of flashover bottle bomb and breakdown leakage of polymer composite insulator appeared in cold ice, freezing rain, fog, wet weather.The safety and reliability had been improved and the service life Heat Management Device had been extended by changing skirt concave to increase creepage distance and increasing joint strength reasonably.
