Nanjing Iron & Steel Group Co., Ltd. was founded in 1958. In July 1996, Nanjing Iron & Steel Plant was restructured into Nanjing Iron & Steel Group Co., Ltd. Since 2002, CEEG has repeatedly won bids in Nanjing Iron & Steel Group’s procurement projects, with a cumulative contract value exceeding RMB 10 million. The product portfolio is diverse, including SCB epoxy resin dry-type transformers and SG10 non-encapsulated dry-type transformers, providing reliable power support for steel production operations.
Qilu Petrochemical Group has shown strong preference for CEEG transformer products, widely adopting multiple series across its plant area. The company has deployed CEEG SRN high-temperature resistant liquid-immersed distribution transformers, 35kV main transformers, and SCB epoxy resin dry-type transformers. The cumulative procurement value has exceeded RMB 10 million, reflecting long-term cooperation and recognition of product reliability and performance.
The Runyang Yangtze River Bridge is one of the most significant bridge engineering projects in China’s history, featuring the largest construction scale, the highest design standards, and the most complex technical requirements among similar projects. Due to extremely strict requirements for electrical equipment such as transformers, CEEG supplied 8 units of SG10 series dry-type transformers and 1 underground prefabricated substation. These products were successfully applied across the project thanks to their reliable quality, environmental performance, and energy-saving characteristics.
The Shenzhen–Hong Kong Cross-Sea Highway Bridge is one of the largest cross-boundary infrastructure projects between Guangdong and Hong Kong, serving as a key transportation link between mainland China and Hong Kong and playing an important role in strengthening regional connectivity. For this project, a centralized procurement of over 20 units of CEEG equipment was carried out, including amorphous alloy oil-immersed transformers, S11-MD underground-type transformers, SCR dry-type transformers, and European-style prefabricated substations. CEEG products were highly recognized by the project stakeholders for their “invisible environmental protection” concept and advantages in safety and energy efficiency, with full satisfaction expressed regarding technical performance parameters.
Shenzhen Metro Phase I Project is Shenzhen’s first national key construction project and also the largest municipal infrastructure investment since the city’s establishment. To ensure safe, efficient metro operation, the project imposed stringent requirements on electrical equipment suppliers. 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.
