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

The utility model provides a 500kV line tension-resistant iron tower with 180-degree rotation angles, which comprises a tower body, and an upper-layer wire cross arm and a lower-layer wire cross arm which are in bilateral symmetry are arranged on the tower body in parallel up and down. Wherein the left end point and the right end point of the upper-layer wire cross arm are provided with a first upper-layer wire hanging point and a third upper-layer wire hanging point respectively, 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 arranged at the left end point and the right end point of the lower-layer wire cross arm res
