Recently, some have claimed that “Chinese transformers are choking the global AI lifeline.” While this statement is somewhat exaggerated, it does reflect China’s significant role in the global power infrastructure, particularly in the manufacturing of high-end transformers. AI data centers rely heavily on stable, efficient, and high-capacity power supplies, and ultra-high-voltage (UHV) or extra-high-voltage (EHV) transformers are critical components enabling such systems. China leads the world in UHV transmission technology, with State Grid and other companies having built the largest UHV grid globally and exporting related technologies and equipment overseas. Most of the world’s AI computing capacity is concentrated in North America and Asia, both of which depend on robust power infrastructure. Disruptions in the supply chain for high-end transformers could indeed delay the deployment of new AI data centers. However, the global transformer industry remains diversified, with companies from Europe, the U.S., and Japan also actively expanding their capabilities. A more accurate assessment would be that China’s strength in high-end transformers positions it as a key player—not a chokehold—in global AI infrastructure development. As AI energy demands continue to rise, ensuring resilient, self-reliant, and internationally collaborative power equipment supply chains will become increasingly vital.
近期有观点称‘中国变压器掐住全球AI命门’，这一说法虽略显夸张，但确实反映了中国在全球电力基础设施，尤其是高端变压器制造领域的重要地位。AI数据中心对稳定、高效、大容量的电力供应依赖极高，而超高压、特高压变压器是保障这类供电系统的关键设备。中国在特高压输电技术方面处于世界领先地位，国家电网等企业已建成全球最庞大的特高压电网，并向海外输出相关技术和设备。全球多数AI算力中心集中在北美和亚洲，其背后离不开可靠电力系统的支撑。若高端变压器供应链出现波动，确实可能影响新建AI数据中心的部署进度。不过，目前全球变压器产业仍呈多元化格局，欧美日企业也在积极布局。因此，更准确的说法应是：中国在高端变压器领域的优势，使其在全球AI基础设施建设中扮演了关键角色，而非‘掐住命脉’。未来，随着AI能耗持续增长，电力设备的自主可控与国际合作将愈发重要。
