Background
With the continuous development of the economic society and the power grid construction of China, the electric load of cities and suburbs is continuously increased, the number of power transmission lines is continuously increased, and the land resources for erecting new power transmission lines are less and less. Especially in the areas with high urban residence density, the design requirements of normal transmission lines cannot be met. In order to reduce the land occupation of the power transmission line, save land resources and reduce cost, a novel tower needs to be designed when the power transmission line is designed.
The existing pole body of the pole tower is generally integrally formed, namely, the radiuses of all sections of the pole body are the same. The radius of the pole body can influence the size of the cross arm, and further influence the length of the power transmission line and the usage amount of the power transmission line. Thus, there is a problem that in some projects, the size of the pole body of the pole tower is not matched with the design of the transmission line, thereby causing resource waste. If the whole pole tower is replaced by the pole body with the smaller radius, the size of the cross arm can be reduced, and further the length of the power transmission line and the using amount of the power transmission line are reduced, but the problem of resource waste still exists when the whole pole body is replaced.

the pole body of the pole tower is divided into three sections, wherein the radius of one section of the pole body provided with the cross arm is smaller than that of the other two sections of the pole bodies, and the radius of the pole body is related to the size of the cross arm, so that the size of the cross arm is correspondingly reduced when the radius of the pole body is reduced, the length of a power transmission line and the using amount of the power transmission line are reduced, and the cost is saved;
because three sections of rod bodies are adopted, when the rod body of the tower is adjusted, only one section of rod body provided with the cross arm needs to be replaced, and the whole rod body does not need to be replaced;
the outer wall of one section of the pole body provided with the cross arm is coated with high-strength fiber resin, the high-strength fiber resin is an insulating material, the charging distance of the pole body caused by windage yaw of a power transmission line can be shortened, and therefore the size of the cross arm can be further reduced.

Detailed Description
To further illustrate the features of the present invention, please refer to the following detailed description and accompanying drawings. The drawings are for reference and illustration purposes only and are not intended to limit the scope of the present disclosure.
As shown in fig. 1, the utility model adopts a multi-stage tower, which comprises a first rod body 1, a second rod body 2 and a third rod body 3;
the first rod body 1, the second rod body 2 and the third rod body 3 are connected in sequence;
the radius of the second shaft 2 is smaller than the radius of the first and third shafts 1 and 3.
Specifically, because three sections of rod bodies are adopted, when the rod bodies of the tower do not match the design requirements of the power transmission line and need to be adjusted, the whole rod body does not need to be replaced, so that the resources are saved, and the cost is reduced. The radius of the second shaft 2 can be reduced to the size required by the design by a plate press or a plate rolling machine, and the radius can also be reduced by other modes, which are not described in detail herein.
