XCA220 completes the world's first high-altitude UHV power project

Qinghai Zeku County is nearly 4,000 meters above sea level. It is the region with the largest temperature difference and the worst climatic conditions in China. From Qinghai to Henan, running through the northwest and Central Plains provinces, the total length of the line is 1578 kilometers. The Qinghai-Henan ±800 kV UHV DC project is the most difficult power engineering project in the world.

On the first day of July, the temperature here plummeted below 0 degrees. A heavy snow shrouded the snow-capped mountains and grasslands. Due to high altitude and low oxygen content, it is said to be the region with the worst climatic conditions in northwestern China. It is here that China and even the world's first UHV channel project dedicated to clean energy delivery - Qinghai - Henan ± 800 kV UHV DC project officially launched.

As the most powerful transportation and installation integrated enterprise in Qinghai, Qinghai Zhicheng Industrial Group dispatched XCA220 all-terrain crane to serve as the main task of tower installation. In the harsh environment, the construction process went smoothly. With the installation of the last section of the tower, the first power tower of this line was successfully completed. The tower is 74 meters high and weighs 63 tons.

It is reported that Qinghai-Henan ±800 kV UHV DC project is the first UHV channel project built in China and even the world for clean energy delivery. The project started in Qinghai and ended in Zhumadian City, Henan Province. The length of the whole line is more than 1,500 kilometers, of which the Qinghai section has a total of 434 towers. During the assembly of the tower, Qinghai Zhicheng Group cooperated with the transmission and transformation in strict accordance with the 12 supporting measures of the State Grid Corporation, using video surveillance equipment for the tower material. , the crane tower, high-altitude assembly, pole assembly, jacking and other processes for all-round control, to ensure that the entire construction process is foolproof.

The chief engineer of the on-site power system introduced: As the most difficult part of Qinghai construction, the most stringent management methods and the most advanced crane equipment are used to ensure safe and efficient construction. For a long time, the extreme environment in the plateau region has brought many challenges and uncertainties to the construction. Therefore, we have strict requirements on the selection of equipment. XCMG crane has always become our preferred brand with safe and efficient characteristics.

It is understood that after the completion of the project, it will further improve the capacity of China's clean energy development and development. It is estimated that 40 billion kilowatt-hours of electricity can be delivered to the Central China region every year. To optimize the national energy structure, ensure safe and reliable supply of electricity, and promote air pollution prevention and control, It is of great significance to stimulate economic growth, help the fight against poverty, and promote the transformation and upgrading of the equipment manufacturing industry.
