To investigate the effects of conductive greases on the current-carrying friction behavior of carbon skateboard/contact wire system, comparative tests were conducted under various lubrication conditions and dry friction. Significant improvements in friction and wear performance were revealed, with coefficients of friction and carbon skateboard wear rates reduced by 31% - 40% and 58% - 82%, respectively, under grease lubrication compared to dry conditions. The temperature rise characteristics of conductive greases correlate positively with their electrical conductivities. Additionally, the contact area between carbon skateboard and contact wire was expanded and sustained by grease application, enhancing interfacial conditions and mitigating abnormal wear risks.
