In the design of 500 kV heavy ice area transmission tower, reasonable selection of tower slope can effectively reduce the cost of the project. Taking the type of 53ZBC33 tower, which is in a 20mm ice area 500 kV transmission line, as an example, a comprehensive calculation of 8 different slopes, which range from 0.09 to 0.16, in 60m, 54m, 48m and 42m body-high transmission towers is carried out. A total of 32 models are established. The construction of the tower is based on steel consumption cost, foundation cost and compensation for the occupied land of the tower foundation. From the price comparison analysis, the optimal gradient of transmission tower varies slightly when the body-high of the tower is different, but the overall optimal slope fluctuates in the range of 0.10 to 0.13. In the design project, the optimal slope of the tower can be quickly calculated by the range of 0.10-0.13.
