中国目前电压等级最高的西北750kV官亭至兰州东输变电示范工程,9月19日在青海省正式开工。这是一项被业界称为”继三峡大型水电站送出工程之后输变电工程方面又一具划时代、里程碑意义的重点工程”,它标志着我国电网输变电电压等级由目前最高的500kV即将升级为750kV,实现历史性跨越。同时,该工程还是目前世界上海拔最高的750kV输变
At present, the highest voltage level in China is 750kV Guanting in Northwest China to Lanzhou East Transmission and Transformation Demonstration Project, and was officially started in Qinghai Province on September 19th. This is one of the industry as “a major hydropower station following the Sewage Project after another landmark and landmark project,” it marks China’s power grid transmission and distribution voltage levels from the highest up to now 500kV upgrade 750kV, to achieve a historic leap. At the same time, the project is still the world’s highest elevation of 750kV transmission
