Power transmission tower

The invention discloses a power transmission tower. The power transmission tower structurally comprises a tower body, a wire stringing device, a base support and a cross beam. The base support and thetower body are welded, the cross beam and the tower body are connected. The wire stringing device and the cross beam are embedded and fixedly connected. When a wire drooping from the wire stringing device is pushed by overhead wind power is rotated, rotation in the same direction can be performed according to rotation of the wire through an outer frame on a rotation disc, and therefore a linkageplate can pull a stretching strip to stretch out along a combination block. Accordingly, a pull-back coil can drive the stretching strip to slide and reset along the combination block when the wire stops rotating, and therefore the combination block can pull the rotation disc to reset, the rotation disc can reversely pay off the wound wire, external wind power can be guided into the stretchable block through an air inlet c
