Tension power transmission tower structure for extra-high voltage alternating current power transmission in extra-heavy ice area

The utility model provides a tension power transmission tower structure for extra-high voltage alternating current power transmission in an extra-heavy ice area, relates to the technical field of design of tension power transmission tower structures, and solves the problem of balance among various limitations when an existing tension power transmission tower structure is applied to the extra-heavy ice area. Comprising three-phase wires, a plurality of bearing areas are evenly arranged in the power transmission laying direction of the three-phase wires, a strain power transmission tower in each bearing area is composed of an independent main tower and an independent auxiliary tower, and the independent main tower bears any two phases of wires in the three-phase wires; the independent auxiliary tower bears the remaining one phase of wire except the two phases of wires borne by the independent main tower in the three phases of wires; compared with the existing tension power transmission tower structure, the tens
