EMU's technical policy

EMU's technical policy

As a modern means of transportation, it brings infinite convenience and quickness to people's lives, which makes our country's time from the south to the north shorten. The common means of transportation allow us to see where its technical policy is mainly expressed.

Manufacturing Technology

Has mastered the world's advanced and mature railway rolling stock manufacturing technology. The Alstoms in France, Kawasaki in Japan, Bombardier in Canada, Siemens in Germany, GE in the US, and EMD in the United States are all world-renowned rail technology equipment manufacturers. They have world-class EMUs and high-power electric power of 200 km/h or over. , diesel locomotive design and manufacturing technology. After arduous efforts, we successfully implemented the transfer of these technologies and brought China's railway equipment technology to the top ranks in the world.

Core Technology

The core technologies of EMUs and high-power locomotives are owned by me. High-speed EMU assembly, body, bogie, traction converter, traction control, traction transformer, traction motor, train network control and brake system and other core technologies, high-power electric locomotive assembly, body, steering Main technologies such as frame, main transformer, network control, main converter, drive device, traction motor, brake system, core technologies such as diesel engine, main and auxiliary generator, and AC drive control of high-power diesel locomotives, and a large number of supporting technologies We have mastered. The localization rate of EMUs and high-power locomotives with a speed of 200 kilometers per hour or more produced using these technologies can reach over 70%.

Low cost

The prices of EMUs and high-power locomotives we introduced are much lower than those in other countries. EMUs are 14% lower than Spain and 20% lower than South Korea. 6-axis high-power locomotives are 44% cheaper than comparable European products. The reason why we can achieve such a high price/performance ratio is that we have made full use of the huge market advantage of China Railways and the advantages of the combination of domestic companies under the leadership of the Ministry of Railways. In addition, we have adopted flexible negotiation strategies to achieve national interests. maximize.

Speed ​​up industrial modernization

Accelerated the pace of modernization of China's rolling stock manufacturing industry. In this large-scale technology introduction, a total of a dozen major locomotive and rolling stock manufacturing enterprises and hundreds of peripheral enterprises benefited directly from China, achieving a leap in the manufacturing level of locomotives and vehicles, enhancing market competitiveness, and effectively promoting China. The development of related national industries. Among these key manufacturing companies, Changchun Railway Vehicle Co., Ltd. has accepted the technology of Alstom and has manufactured CRH5 EMUs; Sifang Locomotive and Rolling Stock Co., Ltd. has acquired the technology of Kawasaki Heavy Industries of Japan and manufactures CRH2 type. EMU; Qingdao BSP Company received the technology of Canadian Bombardier Company to manufacture and manufacture CRH1-type motor vehicle trains; Tangshan Locomotive and Rolling Stock Plant granted the technology of German Siemens Company to manufacture CRH 3-type EMUs; Dalian Locomotive and Rolling Stock Company transferred to Toshiba, Japan; The technology of the company and EMD of the United States produces harmonious type 3 high-power electric locomotives and harmonious high-power diesel locomotives; Datong Electric locomotive company assigns Alstom’s technology to produce harmonious 2D high-power electric locomotives; Zhuzhou Electric Locomotive Company Received the technology of Germany's Siemens Company to produce the Harmony 2Z high-power electric locomotive; Qishuyan Locomotive and Rolling Stock Plant received the technology of the United States GE Company to produce a harmonious high-power diesel locomotive. Yongji Electric Machinery Factory, Zhuzhou Locomotive & Rolling Stock Research Institute, and China Academy of Railway Science and Technology have also acquired advanced traction motors, traction and auxiliary converters, traction control systems and other key technologies to form a new railway vehicle manufacturing industry in China. Industrial clusters.

Creative work

It has made important progress. In terms of EMUs, we are making every effort to promote independent innovations such as large marshall EMUs and sleeper EMUs. At the same time, on the technical platform of 200 km/h, the independently-developed 300-kilometer EMU will be rolled off the line and will be released in Beijing, Tianjin and Wuhan. Beijing, Shanghai and other passenger dedicated passenger lines have become the main models of future high-speed passenger transport in China. For high-power locomotives, on the 6-axis total power 7200 kW technology platform, independent innovation of traction converters, traction motors, bodywork, bogies, and integrated vehicle technologies is being organized. The total locomotive power can be increased to 9600 kW. , become the main model of the future haul freight train.
