The wear of contact strip on the pantograph of electric railway vehicle is mainly governed by arc discharge occurring simultaneously with contact break between strip and trolley wire. Sliding wear tests were carried out under electric current for the combination of Cu-impregnated baked carbon strip and Cu trolley at a sliding speed of 100 km/h. Voltage drop and current were measured at a frequency...
In electric railways, the wear rate of trolley wire decides the life of the wire. In order to search for methods of decreasing the wear rate, laboratory wear test was carried out with three types of wire materials sliding against an iron-base sintered alloy strip under electric current flow condition. The test results indicate that the wear rate of wire is related to heat generated at contact surfaces...
