Abstract

Composite insulators are insulation parts which are used to withstand power load and all kinds of stress applied by wires in transmission lines,the stress offen cause fracture and brittle fracture of core rods in the operation.In this paper,composite insulators, running in the ice coating and wind load conditions of Three Gorgee Area,is chose as the research object.Based on theory of mechanics of materials end experiment results carried out in existing papers and simulation of the bending stress of composite insulators, the stress failure of the insulator (FXBW4-110/70) in 110kV transmission lines were studied.The results show that, under the single action of tension,torsion and bending load,the instantaneous fracture of 110kV suspension-type composite insulators could not happen in the Three Gorgee Area . The line galloping and sleet jump of conductor make the fracture of bent insulators happen in the locations near towers. The results also found that the long-running composite insulators could make stress concentration position shift ,eventually lead to brittle fracture.
