Recently, a Bell 429 helicopter slowly lifted off from the shore of Guanting Reservoir in Huailai County, Zhangjiakou, Hebei Province. The 40-meter-long insulated rope hung from the fuselage accurately and steadily placed the operators and equipment to ±500 thousand. The Fuzhangbei flexible DC power grid projects are all sent to the Yanqing DC line conductors, ready to implement live work to eliminate hidden dangers.
This is the first time that the State Grid Corporation of China has carried out live helicopter operations on Olympic transmission lines, filling the technical gap in domestic helicopter live operations on DC lines of the same voltage level, further testing the power emergency response capabilities, and ensuring the continued stability of green power for the Beijing 2022 Winter Olympics supply.Editor/Baohongying
