Abstract: In recent years,the number of high-voltage transmission cables has increased steadily,and the choice of cable laying methods directly affects the later operation and maintenance mode of the cables.Based on the existing cable operation and maintenance experience,the pros and cons of direct buried cables,protection pipes,cable trenches,tunnels,and jacking pipes laying from multiple perspectives was analyzed in this paper,and a comparative analysis was carried out,a reference method for the selection of cable laying methods under two different sources of capital construction and relocation was proposed,and some precautions of Guiyang high-voltage transmission cable management were introduced,The feasibility is verified by the effect.Select reference for future relocation and new high-low-voltage cable projects in infrastructure construction was provided,and the optimal solution was satisfied for the cable management and maintenance department.
