| Abstract: | Through the analysis on the core brittle fracture of the composite insulators in two 220kV transmission lines,it is roughly ascertained that the reason of the core fracture of polymeric insulator is caused by the acid corrosion dure to the defective sealing at the design should be improved by the manufactories to refrain from the failure of the sealing while the acidproof and corrosion resisting material for the core is chosen.It should put more attention to check of the composite insulators. |
