In the vast land of China, the transmission of energy and electricity has always been the lifeblood of national development. The ±800 kV UHVDC transmission line project from Hami to Chongqing is like a giant dragon, running from east to west and becoming an important link between the energy rich areas in the west and the power demand centers in the east. This project is not only the outstanding representative of the first batch of "Shage famine" large-scale wind power photovoltaic base delivery project, but also shows the vigorous vitality and unlimited potential of China's power industry in the new era.

In this magnificent power corridor, the Gansu section occupies an important position, its length is as high as 1494.3 kilometers, through the vast land of Gansu. It is particularly worth mentioning that one section of the line passing through Subei Mongolian Autonomous County in Jiuquan City is about 138.3 kilometers long. This is not only a simple transmission line, but also a challenging and arduous construction process.

Subei Mongolian Autonomous County, this vast land, most areas are inaccessible no man's land. Of the approximately 138.3 kilometers of the route, nearly 110 kilometers pass through such no man's land. Here, the natural environment is harsh, the wind and sand are raging, and the temperature difference between day and night is huge, which brings unprecedented challenges to the power grid builders. However, it is these difficulties that inspire the power grid builders to have more firm faith and more persistent pursuit.

They are not afraid of difficulties, not afraid of hardship, stick to the desert on the Gobi, with sweat and wisdom to write a moving song of workers. They have overcome many difficulties, overcome the harsh environment, and interpreted the lofty concept of "people's electricity for the people" with practical actions. They use their own hands to contribute to the power industry of the motherland and contribute to the happy life of the people.

In this desolate land, the power grid builders with their tenacity and perseverance, cast a monumental monument. These monuments not only witness their hard work and selfless dedication, but also witness the brilliant achievements and brilliant future of China's electric power industry. They will always be remembered and celebrated along this power corridor that connects east and west. Editor/Xu Shengpeng
