When train stops at an insulated overlap of feeding sections in a DC electrified railway system, heat due to arcing or due to large current flowing between sections sometimes melts and serves the contact wire that supplies electric power to pantographs. Then we developed high-heat radiation catenary whose main equipment is aluminum-case, and which is hard to break by arc. We installed development on the overlap of simple catenary and we performed running tests using a pantograph. From the tests, we confirmed that there is no problem on the point of current collection performance. This paper describes outline of developments and current collection tests.
