When a large-scale data center project in Xinjiang’s Altay Region needed high-capacity power distribution infrastructure, Zhongxin General (ZX Transformer) was selected to supply a batch of S11-6300kVA/36.5kV oil-immersed transformers — a RMB 20M+ contract delivered on schedule in Q4 2025. From silicon steel cutting in our Sichuan factory to a convoy dispatch thousands of kilometers west, this case study documents the full journey: manufacturing process, complete technical specifications, delivery logistics, and the design choices that make this transformer series particularly suited to data center applications. Also available in 33kV, 34.5kV, 35kV and 36kV for international grid standards.
