The cause analysis of broken accident on messenger wire in catenary system

The catenary system used in urban electrification railway have suffered mechanical and chemical stresses. These brought out severe messenger wire problems, these have caused accident. Especially, messenger wire is severely influenced by corrosion, vibration and tension. This paper investigate for the cause analysis of broken accident on messenger wire in catenary system. To analyze the cause analysis of accident, we have conducted experiment such as XRD, SEM, EDX and tensile test.
