Abstract

A power transmission tower with three-phase wires in triangle-shaped cross-arm-sharing arrangement. The power transmission tower comprises a tower body (1), a wire cross arm (2), an upper insulator string (3), and a lower insulator string (4).

One upper insulator string (3) is mounted on an upper plane of the wire cross arm (2), two lower insulator strings (4) are mounted on a lower plane, and the three insulator strings form a "triangle" shape. The tower overcomes, in a cross-arm-sharing arrangement manner, a defect that two layers of wire cross arms are required in a conventional wire triangular arrangement tower to meet an arrangement manner required by an electrical clearance of three-phase wires, the structure height of the tower is reduced while omitting a layer of wire cross arms, and the manufacturing cost is saved.
