The utility model discloses a 220kV-electric transmission line single-return tangent tower used in a wind area with air speed of 32.5 meters per second and altitude below 5500 meters. The 220kV-electric transmission line single-return tangent tower comprises tower legs, a tower body and a tower head, wherein the tower body is a trapezoid tower body. The tower head comprises a ground wire support, a wire cross arm and a crank arm, and is in a wire-glass shape. The wire hanging points of the front end of the ground wire support is of a cantilever beam structure, the wire cross arm is in a triangular cross arm shape, and wires are arranged on the wire cross arm in series in an I-shaped mode. The wire cross arm comprises a wire middle cross arm and a wire side cross arm, the tail end of the wire side cross arm is provided with a side wire hanging angle, the wire middle cross arm is in a mouth-closed trapezoid cross arm shape, and wires are arranged on the wire middle cross arm in series in a V-shaped mode and are arranged horizontally and symmetrically. Connecting legs of the tower body are non-public legs. The 220kV-electric transmission line single-return tangent tower can be used normally under the special environment in the Tibet region, the discharging risks cannot be produced, cost is controlled to the maximum, and the 220kV-electric transmission line single-return tangent tower can meet special application demands of 32.5m/s wind areas and complex climate and topographic conditions.
