Tensile strengh is used for life prediction of overhead conductor damaged by forest fire. But, this method needs very much time and cost because tensile strength is breakdown test. Therefore, the different way of testing method is needed to investigate the abnormality and predict the residual life time of overhead conductor damaged by forest fire. This study was performed to develop the new test method to predict the lifetime of fire damaged conductor in terms of reserch on strength, hardness and sag.
