A single level of anti-rust design will usually lead to serious corrosion of parts of the tower. Based on the distribution characteristics of rust factor, this paper puts forward the concept of graded rust prevention design for transmission tower, and gives specific suggestions for rust prevention treatment. This paper takes a transmission tower as an example, carries out a graded anti-rust design, and takes corresponding treatment measures. The results show that the design scheme can guarantee the same anti-rust life of the whole tower as far as possible.
