Abstract：In this paper, a three dimensional finite element model of tower-conductor-ground wire-insulator-interphase spacer system was established in ANSYS, and the dynamic responses of ice shedding for a typical five span transmission line section under different cases were analyzed for transmission tower-line system. Many factors were considered in the ice shedding simulating analysis, which include the core diameter of the interphase spacer, the quantity and location of conductor phases, thickness of the accreted ice, length of the ice-shedding span as well as the elevation difference. The dynamic responses of jumping heights, unbalanced tension and vertical load at the end of the insulator, and the forces of transmission tower were obtained. Influences of all the factors on the suppressed efficiency of the interphase spacers were mainly studied. For the case of ice shedding of single phase conductor, four arrangement schemes of the interphase spacers were compared for the optimal scheme when considering the suppressed efficiency and the economical efficiency comprehensively. Lastly, the optimal arrangement scheme was determined which can suppress the ice-shedding responses.
