Abstract

Pantograph is set on the roof of Subway. This plays the role of staying proper current on Subway when Subway is running or not. Pantograph includes Slider. Slider is most important part of Pantograph because this part is used to receive current from Contact Wire by dynamic interaction with Contact Wire. In general, material of Slider is steel, copper, or carbon alloy. Especially, SEOUL METRO uses Slider of sintered cualloy, but there is problem. This Slider causes over wearing during rainy season. We should reduce wearing between Contact Wire and Slider. Reducing this wear is most valuable technology in Subway system. I performed experiments to find out the best way that reduces the wear. I can find the best way as I change the rate of the alloy.
