A certain transmission line has spent the largest ice load period safely. As the temperature rose the ice shedding of OPGW occurred in ice melting process which caused clamp failure OPGW dropping and discharge trip. According to the accident site scene investigation clamp material testing and clamp fracture failure analysis were carried out . Combined with the engineering practice technical measures that OPGW single clip will be changed to double clips in the accident line segment are put forward in the paper.
