In view of the problems of current pantograph sliders of electric train，a new pantograph slider is developed for high speed train. The new pantograph slider is consisted of copper，carbon fiber, graphite and etc. The results showed the optimal technique of preparing slider : copper content 78％, carbon fiber content 2％, additive content 5％, pressure 200MPa and sintering temperature 880°C. Its resistance is very low. And its performance of friction，abrasion and impact toughness etc. is improved greatly compared with foreign immersed metal carbon slider Rh82Mb with friction coefficient reduced by 20 %，abrasion ratio decreased by 1.3 %，impact toughness increased by 1.7 times and conductance increased by 65 times.
