Chongqing Yihong Technology Development Co., Ltd.
Focusing on the localization equipment integration of urban rail transit, the company's main product is Yihong pantograph carbon slide, which has achieved standardized and large-scale mass production. The carbon slide is the core component for the train to obtain power. It relies on components such as current collector shoes, slide body, and tie rods to contact the overhead lines to complete power transmission, which is conductive and wear-resistant, protects the contact wires, and adapts to the all-weather operation of the subway. The products have been deployed and put into normal use on the whole lines of Chongqing Rail Transit Line 1, Line 6 and Loop Line, with stable and reliable operation performance.
