Outdoor use over an extended period will be required for supporting equipments for an overhead contact system. Accordingly a damage phenomenon due to corrosion occurs frequently. Especially, corrosion is easy to occur in the salt injury district along the sea shore, and the life of the members of the supporting equipment tends to shorten. Therefore, we examined the extension of service life of the insulation horizontal pipe for overhead contact system by manufacturing it with the SW (Sheet Winding) method. As a result, deterioration of the pipe surface was mitigated by this manufacturing method and there are good prospects of the extension of service life. In this paper, we introduce an outline of the development and the result of exposure tests under electric charge.
