Abstract: In recent years,the wear of the conductor by the pre-stranded anti-vibration damper often occurs in areas with severe breeze vibration,and if the wear is not located in time, the late wear might accelerate, leading to severe consequences such as the strand breakage and even conductor breakage. For different types and manifestations of the wear,by setting different operating scenarios and taking into consideration of different environmental factors, this paper explores the influence degree of the number,diameter and pitch of the pre-stranded rod on the wear,and deeply analyzes the mechanism of the wear development. The experimental research has been performed on the typical conductor and pre-stranded vibration damper,and comparative tests are made with the bolted vibration damper. The results show that in terms of the degree of impact on the gap between the anti-vibration damper clamp and the conductor,the order from high to low should be the pitch,number and diameter of the pre-stranded rod. In the area of severe breeze vibration,the pre-stranded anti-vibration damper should be used with caution. The traditional bolted antivibration damper should be equipped with armor rods in the area of severe breeze vibration. In addition,a specific optimization scheme is proposed for the design and installation of the prestranded anti-vibration damper,which has solved the safety andstability of the pre-stranded anti-vibration damper from atheoretical and practical perspective.
