On Sept 18, along the Huinong-Yinchuan section of the Baotou-Yinchuan high-speed railway, the operation and maintenance personnel of Shizuishan Power Supply Company of the State Grid adopted a "manual + intelligent" mode to inspect the traction substation equipment and power supply lines of the station, providing reliable power support for the official opening of the high-speed railway.

The railway is a crucial component of the Jinglan corridor, a main channel within China's "eight vertical and eight horizontal" high-speed railway network. It is a significant project outlined in the country's 14th Five-Year Plan (2021-25), serving as a vital transportation route within the core region of the Belt and Road Initiative. Additionally, it stands as the first high-speed railway line in China to connect two ethnic minority autonomous regions, spanning a total length of 518 kilometers.

The Huinong-Yinchuan section of the Baotou-Yinchuan high-speed railway originates from Huinong district, Shizuishan city, Ningxia Hui autonomous region, traversing Dawukou district and Pingluo county of Shizuishan city, and culminating in Yinchuan city, Ningxia. Spanning a total length of 99 kilometers, it is designed to accommodate a speed of 250 kilometers per hour. This railway segment comprises four stations: Huinong South Station, Shizuishan Station, Shahu Station, and Yinchuan Station. Upon its opening, this high-speed railway will play a pivotal role in enhancing the railway backbone network in Ningxia, facilitating the development of the pilot area, and promoting high-quality economic and social progress in Ningxia.

To ensure safe and reliable power supply for the traction substation of the Baotou-Yinchuan high-speed railway station, the Shizuishan Power Supply Company of the State Grid invested in the construction of the 220kV external power supply project for the Ningxia Shizuishan South traction substation of the Baotou-Yinchuan high-speed railway. The project, spanning a total length of 27.5 km, involves the construction of 75 new poles and towers, with a total investment of 66.33 million yuan. The project primarily comprises one main power supply line and one standby power supply line, providing dual power sources for the railway, sourced respectively from the 220kV Chengguan substation and Lanshan substation, thereby ensuring the stability of power supply for the traction substation.
