On the first day of the hottest part of summer in July, the temperature here plummeted below 0 degrees, and a heavy snow covered the vast snow mountain grassland. Due to high elevation and low oxygen, this place snow-covered plateau is known as the area with worst climate in the northwest China. However, Qinghai-Henan (+800 KV) UHVDC project, the first UHVDC channel project in China and even in the world officially kicked off.
It is reported that Qinghai-Henan (+800 KV) UHVDC project is the first UHV channel project specially built for clean energy delivery in China and even in the world. It starts form Qinghai and ends in Zhumadian, Henan Province. The total length is more than 1500km, and there are 434 towers in Qinghai section. During the assembly process, Qinghai Zhicheng Group conformed with power transmission and transformation strictly according to 12 supporting measures of State snow-covered plateau Grid Corporation, and utilized video surveillance to control the process of tower material piecing, crane group tower, high-altitude assembly, pole assembly and jacking in an all-round way, so as to ensure the safety of whole construction.
Chief Engineer of Electric Power introduced: as the most difficult section, Qinghai section was constructed with most stringent management method and most advanced crane equipment to ensure the safety and efficiency. For a long time, the extreme environment in the plateau has brought multiple challenges and uncertainties to the construction, so we have strict requirements snow-covered plateau on the selection of equipment. XCMG crane has always become our preferred brand due to its safety and efficiency.
