Abstract: This project aims to enhance the power supply capacity and reliability of the power grid by addressing the issues of outdated equipment and safety hazards on the 10 kV 586 Pan Changying Line and its branch lines such as Cha Laokou. The scope of the project includes a 12.1-kilometer 10 kV line, along with multiple branch lines and corresponding facilities such as poles and conductors. In order to meet the increasing electricity demand in the local area,the main objectives of the project are to optimize the power grid structure, improve power supply reliability, eliminate safety hazards. By adopting new technologies, materials and processes, the project can improve the health level and operational efficiency of the lines effectively, reduce outage time and scope, and provide a more stable and reliable power supply to local residents and businesses.
