Railway Overhead Electric Line Wear Testing Machine

This machine has been developed to simulate the contact between an overhead electric line and the train pantograph contact strip. It is capable of 200km/hour sliding contact speeds. A rotary arrangement of segments from the overhead line is used, loaded by a stationary pantograph contact strip. It is designed for investigating the effects of speed and contact load on both the contact strip and copper wire. The machine includes a 'pocket' into which features such as neural section joints can be installed to study these components under service speeds and loads, but in the controlled environment of the laboratory.
