Sanbian Sci-Tech
Founded in 1968 in Sanmen County, Zhejiang, Sanbian Sci-Tech operates under Chairman and CEO Shangqun Yu as a specialized manufacturer of medium- and large-sized power transformers. The company produces both oil-immersed and dry-type units, supplying the foundational hardware for China's electrical grid expansion. Its headquarters and primary manufacturing base sit along the industrial corridor of Haiyou Town, supported by dedicated new energy and transmission distribution hubs within the county. Sanbian's product line addresses the full voltage spectrum demanded by grid operators and industrial consumers. The company supplies State Grid Corporation of China as a major strategic partner, alongside power equipment agreements with Tesla and Lucid Motors. On the materials side, Sanbian maintains a joint innovation center with Baowu Group for oriented silicon steel development — the core magnetic material in modern transformer design. The firm also partners with Sungrow Power Supply on new energy and energy storage applications, covering solar farm interconnection and battery energy storage system step-up requirements. The company operates four named industrial facilities: its main plant on West District Road in Sanmen, a dedicated New Energy Delivery Center, a Transmission & Distribution Hub, and an Ultra-High Voltage Power Transformer Test Center able to validate equipment for the highest-voltage backbone lines. Sanbian participates actively in the China Chamber of Commerce for Import and Export of Machinery and Electronic Products (CCCME), reflecting an export posture that ships product to international markets beyond China. Unlike diversified industrial conglomerates, Sanbian remains structurally concentrated on the transformer link in the power value chain — a position that makes it a direct participant in infrastructure capex cycles driven by grid investment and renewable interconnection. Its supplier relationships with electric vehicle manufacturers Tesla and Lucid demonstrate a downstream tie to manufacturing electrification that extends beyond traditional utility procurement channels.
