Poles of overhead contact line are designed based on the earthquake resistant guide, but a line hardware or an electric wire often breaks in middle scale of earthquake. In order to analyze the dynamic characteristics of overhead contact equipment under the condition of earthquake excitation, we developed 3-dimensional dynamic simulation method of overhead contact system. Moreover, we carried out bending and stretching tests of stranded conductors and exciting tests of concrete and steel-pipe poles. From these results, it is confirmed that the real bending rigidity and the bending stress of a stranded conductor are lower than that of a single wire. This paper describes the vibration displacement and the material stress of the overhead contact lines and feeders, etc. caused by the assumed earthquake. We propose the earthquake-resistant performance and its improvement methods of overhead contact systems.
