In the transmission line, the distance between adjacent transmission lines should meet the minimum air gap between phases. However, the width of the transmission line corridor is much larger than the minimum air gap between transmission lines. The reason for this is that the overhead bare conductor is used as a high potential, and a certain safety distance needs to be set between the transmission tower body as a low potential.

The interphase width A of the transmission line determines the width of the transmission line corridor. In order to meet the safety of a small area of the transmission tower, the width of the entire transmission line corridor was enlarged.
