Contact Overhead Lines on Shanxi Section of China's Xiong'an-Xinzhou High-Speed Railway Fully Energized

en.Wedoany.com Reported - On November 11, China Railway Taiyuan Group completed one-time energization of the contact overhead lines across the entire Shanxi section of the Xiong'an-Xinzhou High-Speed Railway. The line's power supply system has entered the stage of preparation for dynamic testing, with hot-slide tests and integrated commissioning and testing to follow. This energization covered the entire Shanxi section, officially making the contact overhead lines ready to receive power and providing power support for EMU on-track testing, comprehensive integrated commissioning of railway systems, and subsequent pre-opening inspections.

Contact overhead lines are an important component of the traction power supply system of high-speed railways, responsible for continuously delivering the power needed for EMU operation. During this energization, high-voltage electricity from the local power grid was converted by railway traction substations into 27.5 kV alternating current and then transmitted to the contact overhead lines along the route. During the hot-slide test stage, the focus will be on testing the dynamic interaction between the EMU pantograph and the contact overhead lines, verifying pantograph-catenary current collection performance, and providing a basis for subsequent train operation tests.

The Xiong'an-Xinzhou High-Speed Railway runs from the Xiong'an New Area in Hebei in the east to Xinzhou in Shanxi in the west, and is an important component of the Beijing-Kunming corridor of the national "Eight Vertical and Eight Horizontal" high-speed railway network. The main line is approximately 342 km long, of which the Shanxi section is approximately 242.4 km, with a design speed of 350 km/h. It is Shanxi's first high-speed railway with a design speed of 350 km/h.

Once completed, the line will connect the Xiong'an New Area with Xinzhou in Shanxi and, through the railway network along the route, link the Beijing-Tianjin-Hebei region with central and western Shanxi. At present, energization of the contact overhead lines across the entire Shanxi section has been completed, and the project will subsequently move on to hot-slide tests, integrated commissioning and testing, and operational testing, gradually completing system testing and acceptance work before opening to traffic.
