The purpose of this paper is to propose a new index for the seismic damage estimation of service lines. The proposed index is evaluated based on the tension of each service line due to an earthquake event. Because the tension is evaluated based on not only the seismic intensity, but also the dynamic property of the major components of the distribution equipment including the pole, line, transformer, and service line, the proposed index enables us to quantitatively differentiate the seismic damage level of every distribution pole. On the basis of the seismic damage record caused by the 2007 Niigata-Ken Chuetsu-Oki earthquake, the estimate accuracy of the proposed index is compared to those with existing damage indices. As a result, it was clarified that the proposed index is more appropriate than existing indices for the equipment damage estimation.
