According to the instance of turnover and twist of conductor-spacers system,a question of torsional stability of conductor-spacers system is proposed.The paper analyzes the reason why the torsional instability of the entire system occurs and puts forward that the residual torque moment has existed during the process of conductor stranding,which creates a security risk to the stability of the system.In addition,the torque moment caused by the uneven ice-covering and different periods of ice-shedding will leave the system unbalanced.Finally, methods of improving the stability of conductor-spacers system is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
