Background
The tower type power supply cannot be popularized and applied in the field of field mobile equipment, and people know that the tower type power supply is environment-friendly and economical. Because of the simple tower-type power supply in the practical process, the working radius is determined by the swing radian of the hanging allowance of the cable from the tower cantilever because of the small power supply radius. Typically, a tower of around 10 meters is most economical, so its working radius will not exceed 5 meters. If the working radius needs to be increased, the height of the tower is increased, the general working condition is that the radius is 35 meters, and the minimum length of the tower is more than 70 meters. The investment or the use of the equipment is not very planned. There are many operating conditions that do not have this height and space at all, and it is impractical and possible to raise the tower height to meet the operating conditions. Therefore, the main reason why the common tower type tower cannot be popularized and marketed is that.
