The entire catenary power supply for the Shanxi section of the Xiongxin High-Speed Railway has been completed.

The reporter learned from China Railway Taiyuan Group that in the early hours of November 11, the entire overhead contact system of the Shanxi section of the Xiong'an-Xinzhou High-Speed Railway completed one-time power transmission, laying the foundation for the upcoming hot-slide test and integrated commissioning and testing. Power transmission to the overhead contact system means converting high-voltage electricity from the local power grid into 27.5 kV alternating current through railway traction substations, and then transmitting it to the overhead contact system to continuously supply power to high-speed EMUs. The successful power transmission of the overhead contact system is a key and landmark milestone in the railway project's transition from static construction to dynamic debugging, and is an important prerequisite for the high-speed railway to meet the conditions for dynamic testing and subsequent safe opening and operation.
