From July 10 to 13, the 24th IET International Conference on AC and DC Power Transmission (ACDC 2026) was held in Beijing, co-hosted by the Institution of Engineering and Technology (IET), Tsinghua University and Huairou Laboratory. As a long-standing, top-tier flagship academic and industrial event in the global field of AC and DC power transmission, the conference centered on core hot topics including the construction of new power systems, grid integration of high-proportion renewable energy, and technological innovation of AC/DC power grids. It brought together academicians, leading scientific researchers and representatives of top power enterprises worldwide to conduct in-depth discussions on development paths for power transmission technological innovation, industrial upgrading and low-carbon energy transition in the new era, building a high-end platform for exchange and cooperation to drive technological iteration and coordinated development of the global power and energy sector.

Following the general trend of energy transformation, SUNKING.TECH., which has long focused on core power electronics, made a prominent appearance at the conference. The company showcased five self-developed core product lines: anode saturable reactors, DC link capacitors, solid-state circuit breakers, online monitoring systems and grid impedance measurement equipment. It presented a full-range one-stop integrated solution of power electronic devices applicable to all AC/DC power transmission scenarios and the construction of new power systems, fully demonstrating the enterprise’s robust technical strength and innovative achievements in the localization, intelligence and low-carbon development of core power equipment.

Tong Kefeng, Deputy General Manager of Ningbo Hairong Electric Co., Ltd, a subsidiary of SUNKING.TECH., delivered a presentation on the R&D progress and future development trends of dry-type DC link capacitors for flexible converter valves. China’s flexible DC power transmission technology for smart grids has taken a global lead, accompanied by rapid market expansion. Supported by State Grid Corporation of China and China Southern Power Grid, capacitors applied for flexible DC transmission have achieved rapid development and deployed in batches for the Gansu-Zhejiang Power Transmission Project. Multiple technical routes are available for further innovation and breakthroughs in capacitors for flexible DC transmission, leaving ample room for joint innovation across the entire industrial chain, including end users, material manufacturers, equipment suppliers, capacitor producers and testing institutions. China’s capacitor industry is poised to achieve a leap to global leader.

At the exhibition, SUNKING.TECH.’s cutting-edge technical solutions, mature product portfolio and solid R&D capabilities drew extensive attention from numerous domestic and overseas academicians and industry practitioners. All core products on display are developed based on SUNKING.TECH.’s proprietary core technologies, tailored to address key industry challenges including high-voltage AC/DC power transmission, grid integration of renewable energy, stable grid operation and intelligent equipment operation & maintenance.
