Abstract

Development of single copper feeder messenger wire for overhead contact lines A. Iwainaka\ A. Suzuki*, & Y Shimodaira^ * Railway Technical Research Institute, Japan ^East Japan Railway Company, Japan Abstract Feeder messenger wire type overhead contact lines are drawing attention recently from the viewpoint of laborsaving for maintenance. Those that use two PH356mm^ messenger wires are introduced in Tokyo, and those that use an SB- TACSR730mm^ messenger wire are in the Kansai district. Regarding the number of messenger wires, the one-wire system is more advantageous, as it involves a smaller number of parts. As the material for the wire, copper is more advantageous than aluminum, since it does not require connection with different metals. To realize the advantages of the two systems, therefore, we developed a feeder messenger wire type overhead contact line which has only one copper messenger wire. 1 Introduction Feeder messenger wire type overhead contact lines
