Abstract: To address issues such as complex 10 kV line route layout, susceptibility to cross-interference during on-site construction, and vulnerability to damage during towing and laying, this study designs a three-dimensional towing system based on building information modeling (BIM). Through BIM geometric modeling and collision analysis, a safe, efficient, reliable, and economical line route plan is developed. Parameter simulation calculation and dynamic simulation optimization are then used to continuously adjust the towing and laying route and determine the optimal construction scheme. The proposed approach improves the safety and economic benefits of 10 kV line construction and provides a reference for similar projects.
