2025 China International Urban Rail Transit Exhibition
On September 18th, the 2025 China International Urban Rail Transit Exhibition and CAMET Forum (referred to as MetroTrans 2025), hosted by the China Urban Rail Transit Association, grandly opened! As the first professional international exhibition platform for urban rail transit in China, MetroTrans 2025, with the theme of "Innovation to Break Through and Move towards a New Stage of Urban Rail Transit Development", focuses on the directions of high-end, intelligence and scenario-based development, and creates an innovative display matrix covering the entire industrial chain. At this exhibition, Xinfangsheng Qingdao Company showcased its new-generation rail transit flexible power supply system - "Bidirectional Converter Device" in the green section of Qingdao Metro.
1. Technology-driven, the proactive flexible power supply system solution has attracted much attention.
In the rail transportation industry, FGI is one of the earliest enterprises in China to research and manufacture regenerative braking energy absorption devices. In 2019, it also took the lead in drafting the national standard for regenerative braking energy absorption devices. As of now, the company's rail transportation products, totaling over 500 units, have been stably put into operation in 45 subway lines across 20 cities in China.
The FGI new-generation flexible power supply system for rail transit - the "bidirectional converter device" integrates rectification and inversion functions. It adopts a liquid-cooling high-efficiency heat dissipation method and is equipped with an energy management system to achieve coordinated control of multiple machines in parallel. Compared with traditional solutions, it significantly reduces the floor space, decreases the system investment scale, simplifies the complexity, and makes the power supply system more energy-efficient and effective.
2. Deep interaction, industry-university-research collaboration to jointly explore new tracks
During the exhibition, the FGI team had in-depth discussions with domestic and foreign experts, scholars, and peers on topics such as technical solutions and industry development trends. The FGI Qingdao Company will continue to drive innovation through technology, promoting the application of advanced energy-saving technologies in a wider range of fields. These technologies, which have both significant social benefits and good economic benefits, will better serve the country's green development strategy and the sustainable development of the economy and society.
3.Future Outlook: Focus on "Green Intelligence Integration" to Drive Industrial Upgrading
Through this exhibition, FGI will take the opportunity to further expand its layout in the four strategic sectors, continuously optimize core technologies such as flexible power supply, energy recovery, new energy integration, and hydrogen power supply, consolidate the rail transit market, vigorously expand applications in ports and airports, and actively explore international opportunities, in order to provide solutions for the intelligentization and green transformation of the global rail transit industry.
