Design and Implementation with Enclosed Automatic Mobile Factory for UHV GIS

The installation of ultra-high voltage GIS of enclosed mobile workshop is a new type equipment installation for outdoor GIS. In the fully enclosed environment onsite, it overcomes the impact of external environment on GIS installation and ensures the quality. Based on the background and the structural, it forms the application method in the engineering situation. The fully enclosed mobile factory installation of ultra-high voltage GIS has been tested and promoted in some provinces in the east of China. The total length of the Anhui power transmission project is 656 kilometers, and the substation capacity is 21 million KVA. The Zhejiang-Fuzhou ultra-high voltage AC transmission and transformation project has a total length of 2×603 kilometers, a substation capacity of 18 million KVA, and the whole line is erected with the same tower and double circuit. They have been determined to be widely used in all subsequent ultra-high voltage AC projects and achieving very good results.
