The authors have examined the direct bonding of contact strip with glue as one of the ways to attach the metal-impregnated carbon strip to pantograph head. For practical application of this method, it is essential that the base-surface temperature of the strip does not reach the heat-resistant temperature of the glue when the strip is collecting current from the contact wire. In order to investigate the temperature rise of the strip under several conditions, the authors carried out sliding-contact experiments with electrical current and simulated the experiments with Finite Element thermal analysis. According the results of the experiments and the analysis, the base-surface temperature of the strip during collecting the current in normal application is assumable lower than the heat-resistant temperature of the glue.
