Abstract

The Jakarta MRT (mass rapid transit) is an electric railway train with a track length of 16 km that runs from the Lebak Bulus station to the Hotel Indonesia roundabout station. The main component of the electric railway train is the pantograph, with a voltage source of 1500 Vdc leading to the train motor traction, part of the pantograph that is directly related to the upper flow of electricity is the main contact strip. Increase the use of domestic components by replacing imported product main contact strip components with local product main contact strips. Therefore, this study aims to compare main contact strip wear rates between local and imported products. The data in this study were obtained from Daily Maintenance in the form of kilometer data and wear rate data. Data analysis uses a simple linear regression method which aims to find a comparison between the wear rate and kilometres of main contact strips of local products and imported products. Based on the results of the analysis, it is found that the wear rate of the main contact strip of local products is better than that of imported products. While the service life of the main contact strip since the first kilometer of operation on local products is more durable than imported products.
