The train fully adopts the design concept of standardization, modularization and generalization, which is convenient for maintenance and reduce operation cost. Energy absorbing structure and anti climbing device are set at both ends of the vehicle body, and the longitudinal static load of the vehicle body is 80 tons, which greatly improves the safety of the vehicle. The electrical system adopts the world's most advanced VVVF drive control technology, the welding process adopts the European en15085 welding standard and the din5510 standard with the most stringent fire protection requirements. The train integrates the new structure, new technology and new materials of metro trains developed in China for many years. The layout is reasonable, comfortable, safe and reliable, and the design and manufacturing technology has reached the world-class level. Our company is mainly responsible for providing aluminum alloy profiles for car body in this project.
