Abstract: Taking the Renewable Energy 220 kV Transmission Project in Shunyi, Bejing as an example, this paper summarizes the commonly used live-line crossing construction schemes based on extensive research into transmission line crossing construction methods. This paper compares and analyzes the characteristics, performance, and applicable conditions of crossing frames and protective netting, establishing an optimal selection approach for their deployment. The structural design of the protective netting is optimized through practical cases to enhance its convenience and safety. BIM modeling technology is applied in the selection of crossing frames, analyzing three existing crossing methods. In actual engineering, protective netting and crossing frames are influenced by environmental and climatic factors, therefore regular monitoring is necessary to ensure safety. The effective applications of protective netting and crossing frame technology are crucial for the implementation of projects, while also providing valuable practical experience and reference for future similar projects.
