A certain 220 kV transmission line intersects with the transmission channel and then immediately turns left across110 k V line after crossing 500 kV Ⅰ line

with the characteristics of small side low drilling and large side high crossing. The conventional pole tower arrangement is difficult to cross the span. In view of this difficulty

a new type of traversing tower is designed by using three-dimensional design technology to construct a three-dimensional model of real engineering scene.Comparing various tower types

a new type of crossing towers are designed. The traversing tower is arranged through the front and rear cross-loading layers

and the front side is drilled and the back side is crossed. It has two functions of low drilling and high crossing on the same base tower. There is an adjustable height tower between the upper and lower traverse poles

and the crossing height is adjustable. The use of the pole tower is flexible and applicable.
