Abstract: Abstract: A core mission of the power industry is to ensure uninterrupted power supply and reliable operation of system components, promptly address technical failures, and implement preventive and troubleshooting measures. In distribution line construction management, it is essential to simultaneously process and analyze vast amounts of diverse data while balancing economic and ecological considerations. Therefore, modern technological solutions are urgently needed to support distribution line construction management. As a critical tool in planning, reliability analysis methods can also be applied to evaluate the effectiveness of construction technologies. This study focuses on 10kV distribution lines, employing the "block diagram method" from reliability structural analysis to treat construction systems as integrated entities composed of interconnected elements with specific reliability relationships. Through analyzing construction plans for two loop network feeders (supplying power from different 10kV voltage sections), the research highlights the application of key construction technologies. Results demonstrate that strategically deploying equipment installation techniques such as sectionalized reclosers and loop network reclosers, along with optimized construction plans, can significantly enhance the operational reliability of distribution lines.
