Abstract: Steel pipe poles are increasingly utilized in the relocation and modification design of overhead transmission lines due to their advantages, such as small footprint, simple structure, and the ability to be deployed along green belts or sidewalks of roads. Using the pole and tower design module of a transmission line structural design system, this paper takes 110 kV overhead transmission line steel pipe poles as an example to calculate, compare, and analyze the influence of factors such as nominal height, deflection angle, safety factor, and span on the pole weight. The results indicate that the degree of influence of these factors on pole weight, in descending order, is: safety factor, deflection angle, nominal height, and high-voltage span. The research findings can provide a reference and decision-making basis for transmission line design personnel.
