500kV line tension-resistant iron tower with 180-degree rotation angle

The invention discloses a 500kV line tension-resistant iron tower with a 180-degree rotation angle. The 500kV line tension-resistant iron tower is provided with a tower body, and an upper-layer wire cross arm and a lower-layer wire cross arm which are symmetric left and right are arranged on the tower body in parallel up and down. A first upper-layer wire hanging point and a third upper-layer wire hanging point are correspondingly arranged at the left end point and the right end point of the upper-layer wire cross arm, the horizontal heights of the first upper-layer wire hanging point and the third upper-layer wire hanging point are the same, and a second upper-layer wire hanging point is arranged in the middle position where the connected straight line of the first upper-layer wire hanging point and the third upper-layer wire hanging point intersects with the tower body. A first lower-layer wire hanging point and a third upper-layer wire hanging point are correspondingly arranged at the left end point and th
