The first 800KV tank circuit breaker with independent intellectual property rights independently researched, developed, designed and manufactured by Xidian Xikai High Voltage Electric Appliance Co., Ltd. was approved by the Xidian Group on the 18th and officially delivered to the Northwest Yinchuan East Project. This marks that China's UHV power transmission and transformation equipment manufacturing industry has successfully broken the monopoly of a small number of international enterprises on the complete set of switchgear technology, and ranks among the world's advanced level. The successful development of 800KV switchgear will provide economical, reliable and technically reliable equipment support for China's 750KV power grid and even UHV power grid construction.
The independent research and development and manufacture of 800KV UHV switchgear is one of the important contents of the national promotion of major key equipment technology and equipment. In March 2004, the National Development and Reform Commission organized the project, and the State Grid Corporation and Xidian Group Xikai High Voltage Electric Appliance Co., Ltd. Ltd., Xi'an High Voltage Electric Apparatus Research Institute and Xi'an Xidian High Voltage Switch Co., Ltd. signed a special national technical equipment development and major technology development special contract, which opened the curtain of domestic independent research and development of 750KV power transmission and transformation equipment. In 2006, the project successfully passed the prototype appraisal and acceptance work organized by the State Grid Corporation of China, and was highly praised as “leading international and filling the domestic gapâ€.
