The CR450 EMU prototype was released globally
On December 29, the CR450 EMU prototype was officially released in Beijing, which quickly attracted the attention and reports of domestic and foreign media. The CR450 EMU technology has achieved a comprehensive iterative upgrade, breaking through the three complete sets of technologies of drag and consumption reduction, vibration and noise reduction, and all-factor lightweight system integration, and the three system technologies of high-power permanent magnet traction, time-sensitive train network communication, multi-level control and braking, as well as a number of key technologies such as high-critical speed and high-safety bogie. The train has the characteristics of higher speed, safer, more energy-saving, more comfortable and more intelligent, and has built a technical system for EMUs with a speed of 400 kilometers per hour, realizing comprehensive innovation in theory, technology, equipment, standards and management models, and injecting new vitality into promoting the technological innovation and development of high-speed rail in the world.
Released the world's first serialized new energy locomotive
03 Diesel locomotives exported to Kazakhstan trunk line freight rolled off the assembly line 04 The first new intelligent heavy-duty electric locomotive rolled off the assembly line 05 Train Autonomous Operation System (TACS) Successfully Passed the "Big Test" 06 The first new energy intelligent intercity city EMU was released 07 A new generation of energy storage system CESS-4.0 Solution release On September 2, CRRC released a new generation of energy storage system CESS-4.0, which consists of a ≥ 6.9MW booster converter integrated machine, a ≥6.9MWh energy storage battery compartment and supporting EMS. Equipped with three "black technologies" of self-defined 688Ah cells, energy storage direct coolers, and one core, one management CCS+ technology, it has been updated and upgraded in multiple dimensions, bringing customers a more efficient, safer, smarter, and more flexible all-scenario energy storage integrated solution. 08 A new hopper car was released On September 10, the KM82 composite coal hopper truck officially rolled off the assembly line. For the first time, the car realized the application of carbon fiber composite materials to the main bearing structure of heavy-duty railway wagons, and the first time to integrate the application of on-board intelligent monitoring system in China's railway wagons, marking a major breakthrough in the field of manufacturing and R&D and application of new materials for heavy-haul railway mobile equipment in China. 09 The 20MW floating wind turbine "Qihang" was released 10 Facing the deep sea The 25MW ultra-high power density semi-direct drive generator was unveiled On September 24, at the International Wind Energy Exhibition in Hamburg, Germany, CRRC's 25MW offshore semi-direct drive permanent magnet synchronous wind turbine was officially released. For the development of the deep-sea floating operating environment, the generator and gearbox adopt an innovative integrated design, which has the characteristics and advantages of high integration, high system matching, high reliability, low temperature rise and low vibration. At the same time, it integrates the operation and maintenance concept of intelligent monitoring to ensure the efficiency and accuracy of the operation and maintenance process. It is a milestone in improving China's offshore wind power equipment capacity and improving the ability to develop marine resources.
