A Study on the Performance Improvement of Pull-off Fitting for Catenary

This paper presents the results of materials and mechanical analyses and performance improvement of pull-off fitting used for catenary. The pull-off fitting is supporting the trolley wire which supplies the electricity. However, the pull-off fitting is repeatedly suffered by the mechanical stresses which produce cracks in the swivel clip, resulting in interruption of an electric car. The characteristic analyses of the swivel clip were performed and the improved swivel clip was suggested.
