Jiangsu Daquan Closed Bus Co., Ltd. (formerly Jiangsu Yangtze River Watt Electric Co., Ltd.) was founded in 1994. It belongs to the former Jiangsu Yangtze River Electric Group. It is a large-scale enterprise specializing in manufacturing closed bus in China's power system. Since the company began to study, design and manufacture the closed bus, it has continuously introduced advanced equipment and technology, and has successively introduced advanced technology, production and testing equipment with international standards from Germany, the United States, Sweden and other countries. In 1998, Emform Bus Design and Manufacturing Technology was introduced into China, and it became a manufacturer that introduced foreign advanced technology into Chinese busbar manufacturers. The company has two sets of complete imported assembly line equipment, advanced processing equipment, perfect detection system, but also for the production of first-class quality products to provide a solid and powerful guarantee. The company has passed the certification of ISO 9001 quality system, ISO 14001:2004 environmental management system and OHSAS 18001:2001 occupational health and safety management system.

Since its establishment in 1994, the company has been making progress, pioneering and innovating and keeping pace with the times. Developed into a well-known Enclosed Busbar manufacturer. The annual production capacity of the company is 600 million, and the domestic market share is more than 55%. The performance of the company is in the leading position in the same industry in China. The company is a domestic manufacturer that has designed and manufactured super-long vertical section busbar, and also a domestic manufacturer that has designed and manufactured busbar for more than 700 MW units and has achieved good performance in operation. Since the beginning of research and design of closed bus, more than 600 sets of closed bus have been designed and manufactured with different capacity water, fire, nuclear power units and pumped storage power stations of 200MW-1000MW at home and abroad. The products are famous for their excellent design, excellent quality and excellent service, and have achieved outstanding sales results, such as the world-famous Three Gorges Hydropower Station (26 *840 MW), Huaneng Yuhuan Power Station (4 X1000 MW), Zouxian Power Station (2 X1000 MW), and Xin'an Hydropower Station with large drop of closed bus in China. Jiang Power Plant (9 x90MW), Arak Power Plant (2 x330MW) in Iran, Qinshan Nuclear Power Plant (1 x700MW), Central Java (2 x300MW) in Indonesia, Banglang Hydropower Station (4 x85MW) in Myanmar, Burke (1 x600 MW) in the United States, Boxia River Hydropower Station (2 X110 MW) Jiaxing Power Plant (4 x600MW) in Vietnam, Quinara in Australia Cheng, Tuoketuo Power Plant Phase II, III and IV (6 x600MW), Longtan Hydropower Station (7 x700 MW), Fengning Pumped Storage Power Station 12 * 300 MW, Huizhou Pumped Storage Power Station 8 * 300 MW, Baoquan Pumped Storage Power Station 4 * 300 MW and other major projects.
