Friction and Wear Behaviors with Electric Current of Carbon Strip /Copper Contact Wire for Pantograph /Centenary System

Tao Ding, Yumei Li, Gang Xu, Yi Yang, Qiudong He


The service life of pantograph/catenary system directly affects the stable operation and steady current-receiving of the electrical locomotives. A series of tests were carried out to study the friction and wear behavior of carbon strips and copper contact line using a high speed line-on-block tester. The friction and wear behavior of carbon strips/copper contact line are significant affected by normal load, electric currents and sliding speed. By comparing the different worn microscope of carbon strips, it can be found that the abrasive wear, adhesive wear and arc ablation are mainly wear mechanisms.
