Qinhuai Data's 220kV substation put into operation in 6 months, setting a new record for data center industry delivery

On February 13, Qinhuai Data Group's Lingqiu 220kV substation project in Shanxi officially went into operation. The project took only 6 months from the start of construction to commissioning, setting a new record for the data center industry. The substation that was put into operation this time provides a power supply capacity of 360MW for Qinhuai Data's largest single-site data center in Asia Pacific, providing strong support for the safe operation of the business and laying a solid foundation for the future sustainable development of the largest single-site data center in Asia Pacific.

According to Zhang Binghua, Chief Technology Officer of Qinhuai Data Group, The Qinhuai Lingqiu 220kV substation uses a self-developed high-impedance split-winding transformer patented technology. While ensuring reliable power supply, it eliminates the 110kV voltage level, reduces primary voltage transformation, and achieves high-capacity power directly stepping down from 220kV to 10kV load power supply. This is the first backbone network patent in the data center industry; Compared with the traditional two-stage transformer scheme, it reduces the footprint by about 60%, significantly reduces construction costs, improves power conversion efficiency, and has excellent economic benefits. At the same time, the substation adopts modular technology, and factory prefabrication strictly controls product quality, greatly shortening the construction period and making agile delivery of the substation possible. The successful implementation of this technology has extremely high reference significance for the design and construction of ultra-large-scale data centers and is suitable for various large-scale data center self-owned substation projects. The patented technology fills the gap in the data center industry.
