Problems solved by technology
[0002] At present, when carrying out long-distance transmission of electric energy, the transmission line is mainly suspended by the transmission tower with a large metal frame structure. The reason is that it is very easy to cause icing on the surface of the transmission tower. When the amount of icing is too large, it will seriously threaten the operation safety of the transmission tower. The towers have no active anti-icing function, and are only constructed based on calculated theoretical values. Therefore, the resistance to changes in the natural environment is low, and it cannot effectively prevent the icing phenomenon of transmission towers. Therefore, it is necessary to design a new transmission tower
