Abstract: In view of the single side falling off failure occurred in the spacer rod of a “three-span” power transmission line, the dimensional inspection, physical and mechanical test analysis, field vibration measurement and simulation research are carried out. Based on the failure reason, the prevention and treatment of unilateral shedding of interphase spacer rod is proposed.

Key words: transmission line, three spans, wire spacer, the failure of falling off, loose bolt
