China's first self-developed domestic Taiwan UHP 800 kv double circuit breaker fracture Tank, 18 in China, the West Gate opening Group of High Voltage Electric Co. factory.  This product technical parameters leading to the international level, it successfully developed the international break on a handful of business-to 800 kilovolts switching equipment manufacturers monopoly, improve our switching equipment manufacturing standards. 

   Earlier, the 800-kilovolt high-voltage switching equipment, domestic enterprises can not manufacture, at the international level three or four fracture fracture breaker, relatively backward technology, the situation has hindered the development of China's power industry. As the backbone of China's switching equipment manufacturing enterprises, Xi'an High Voltage Electric Co. opened in September 2003 from the beginning of independently developed, after years of assiduous research and development personnel to tackle the problem, has completed a prototype Manufacture, assembly and test a series of pilot projects.  In July 2006, the SDRC products through national organizations acceptance.
