Wuhan Changhai Electric Technology Development Co., Ltd. (Wuhan Changhai Electric) is a subsidiary of the 712 Research Institute of China Shipbuilding Industry Corporation, located in Wuhan *** High-tech Development Zone—Wuhan East Lake High-tech Development Zone. The company is a high-tech enterprise dominated by the research, design, production and service of electrical products (power system automation devices, switchgear, electronic power equipment). The company has always adhered to science and technology as the guide and innovation as the banner to promote the rapid growth of the industry, and has formed three major industrial sectors: "high-current switch series, rolling stock electrical appliances, and rail transit DC traction power supply systems."
Wuhan Changhai Electric was formerly the Switchgear Division of the 712 Research Institute. Since the institute was founded in 1963, it has developed various types and specifications of DC switches for the military. It is still the *** unit in China developing new high-current DC switchgear for naval ships, and its R&D level is in a * position. In terms of short-circuit switches for copper electrolysis, Germany's Ritter and the United States' Watterdge, under competitive pressure from our company's products, have been forced to withdraw from the Chinese market. The DC traction power supply system independently developed by our company has successively won bids for metro projects such as Phase II of Wuhan Metro Line 4, Wuhan Metro Line 3, and Wuhan Metro Line 6, opening up a path for the localization of China's metro traction power supply systems.
Wuhan Changhai Electric adheres to the business philosophy of "striving for excellence and creating a brand", puts people first, and practices scientific management, committed to building itself into China's * strongest professional supplier in the field of DC electrical appliances.
Today, the rapidly growing Wuhan Changhai Electric will provide every employee with an infinitely wonderful stage, on which every employee will fully unleash passion and talent! We sincerely welcome outstanding talents to join the 712 Research Institute—Wuhan Changhai Electric, and jointly forge dreams!
