CEEG SZ11-31500/110 series transformers stood out due to their safety, reliability, environmental performance, and strong brand reputation, successfully winning the bid. The total contract value reached RMB 12.57 million.
Beijing Capital International Airport is one of China’s most important aviation hubs in terms of geographic location, scale, equipment completeness, and transportation volume, and is among the busiest large international airports in the country. During the selection process for electrical equipment such as dry-type transformers, the airport construction headquarters evaluated multiple suppliers. CEEG SG10-400/10 and SG10-500/10 dry-type transformers stood out in the competitive bidding due to their safety, green design, and environmental performance, ultimately being selected for the project.
Guangzhou New Baiyun International Airport is China’s first large-scale international airport designed, constructed, and operated based on the hub airport concept. During the selection process for dry-type transformers, Guangzhou Baiyun International Airport Co., Ltd. selected CEEG SG10 non-encapsulated H-class dry-type power transformers due to their safety, green design, and environmental advantages, successfully winning the bid. Since being put into operation, the transformers have maintained stable performance and have received consistent positive feedback from relevant operators.
Wuxi Rail Transit is the urban rail transit system of Wuxi, Jiangsu Province, China, constructed and operated by Wuxi Metro Group Co., Ltd. The Wuxi Metro Line 1 officially opened for trial operation on July 1, 2014, with a total length of 29.42 km and 24 stations. Wuxi became the fourth non-provincial capital city in China, after Shenzhen, Suzhou, and Ningbo, to independently operate a metro system. The Wuxi Rail Transit project adopts CEEG 110 kV traction transformers. The products feature low losses, low partial discharge, and strong short-circuit withstand capability, earning high recognition from customers for their reliable performance.
Wuhan Yingwuzhou Yangtze River Bridge is located 2.3 km upstream of the Wuhan Yangtze River Bridge. It connects Yingwuzhou Avenue in Hanyang District on the north bank with Fuxing Road in Wuchang District on the south bank. As Wuhan’s eighth Yangtze River bridge, its main deck carries eight lanes in both directions. It is the world’s first three-tower, four-span suspension bridge with continuous main cables, and also the longest-span bridge of its kind globally. The project adopts CEEG underground-type prefabricated substation series. The product features low noise, environmental friendliness, a unique ventilation structure, high reliability, and easy installation, ensuring stable and efficient power supply for the bridge infrastructure.
Xiong’an Railway Station is located in Xiong County, Baoding City, Hebei Province, China. It primarily serves the Xiong’an New Area and functions as a key interchange station for several major rail lines, including the Beijing–Xiong’an Intercity Railway, Beijing–Hong Kong High-Speed Railway, Tianjin–Xiong’an Intercity Railway, Xiong’an–Shijiazhuang Intercity Railway, and Xiong’an–Xinzhou High-Speed Railway. It is currently recognized as the largest high-speed railway station in Asia. CEEG has supplied multiple 2500 kVA amorphous alloy transformers to support the reliable power infrastructure of Xiong’an Railway Station, contributing to its safe and stable operation.
Jinan Yellow River Tunnel, also known as the Jiluo Road Crossing-Yellow River Tunnel, is regarded as the “First Tunnel under the Yellow River.” It is the largest shield tunnel under construction in China and the first combined road and metro tunnel crossing the Yellow River. The project adopts CEEG SC series epoxy resin dry-type transformers. The products feature strong environmental adaptability and are particularly suitable for applications with significant seasonal load fluctuations or frequent overload requirements, ensuring stable and reliable power supply for the tunnel system.
Beijing Daxing International Airport, also known as Beijing’s Second International Airport or Beijing New Airport, is located to the south of the capital, approximately 46 km in a straight line from Tiananmen Square. Situated at the core of the Beijing–Tianjin–Hebei region, it is a 4F-class international airport, a world-class aviation hub, and a new engine for national development. The airport has been recognized by The Guardian as “the first of the Seven Modern Wonders of the World,” standing alongside globally renowned engineering landmarks such as the Kingdom Tower in Saudi Arabia and the Hong Kong–Zhuhai–Macau Bridge.
