Feasibility Study of Copper-Clad-Steel Conductor as Messenger Wire for High Speed Electric Railway

초록

As the increase of demands for environment-friendly railway system, bronze wires with cadmium as an addictive are no longer permitted as messenger wire for high speed electric railway. This study deals with design and feasibility of messenger wires stranded by copper-clad-steel conductor(CCSC), as the replacement of conventional bronze messenger wires. Two types of CCSC messenger wires were designed to be satisfied with the requirements for high speed overhead contact line and evaluated in the view of the mechanical and electrical properties. And, in order to investigate their thermal expansion behaviours and intro-operability with fittings and contact wires, a trial overhead contact line employed with the CCSC messenger wires and data acquisition system are prepared and supposed to accumulated the data over the year.
