The Shandong section of the Jizheng High-speed Railway reaches a new milestone: Catenary power transmission is ready to achieve a new breakthrough in power!

It was reported on August 28 that the China Railway Construction Electrification Bureau successfully completed the power transmission task of the contact network in the Shandong section of the Jizheng High-speed Railway, laying a solid foundation for the upcoming joint debugging and testing phase.

The technological breakthrough of high-speed rail lines means that high-voltage energy can be obtained from local power grids along the line, and converted into 27.5 kV single-phase power frequency alternating current through the railway traction substation, and then transmitted to the high-speed rail Catenary above the line. This provides reliable power support for the operation of high-speed rail trains, and also marks that a key process before the joint debugging and testing stage has been completed

According to the editor’s understanding, Jizheng The high-speed railway will connect Jinan, the capital of Shandong Province, and Zhengzhou, the capital of Henan Province. It will be constructed in two sections. Among them, the Puyang to Zhengzhou section was put into use on June 20 last year, while the Shandong section is expected to be officially opened for operation at the end of November this year. The new stations in the Shandong section include Changqing Station, Chiping South Station, Liaocheng West Station and Shenxian Station. The main structures of these four station buildings have been completed and are currently entering the decoration stage.

Jizheng The opening of high-speed rail will bring obvious travel convenience. By then, the travel time from Zhengzhou East Railway Station to Jinan West Railway Station will be shortened from the current 3-5 hours to only 1.5 hours. This will become an efficient passenger transportation channel between the Central Plains urban agglomeration and the Shandong Peninsula urban agglomeration, providing citizens with better travel options. A faster and more convenient choice. This traffic improvement measure will also help further promote the integrated development of the regional economy

The construction of the Jizheng High-speed Railway has made significant progress after the successful application of catenary power transmission technology. With the gradual launch of joint commissioning and joint testing, people will enjoy the convenience and speed brought by this high-speed rail line in the future
