Overview of pantographs for China EMU

The CRH series has been the basis for continuous innovation in high-speed trains in china. Pantograph as a crucial electrical connection component have also evolved in this process.The pantographs play a important role in receiving high power from the contact network for the single-phase AC 25kV high voltage power required by the rolling stock. The total traction power required by high-speed trains is much greater than that of ordinary trains. At higher speeds, the air resistance also increases. Considering the requirements of reducing air resistance and noise, the number of pantographs on high-speed trains should not be too many. For 8-car trains, China adopts the single-arch pantograph method, i.e., only one pantograph is used during the operation of the trains and considering the requirements of reliability and redundancy, two pantographs are installed on each train. When the rolling stock is in process, one of the pantographs can be selected to be raised and the other pantograph folded.
