An angle tower for charging, breaking and leading-down of a single-circuit overhead transmission line cable comprises a tower body, a top layer ground wire cross arm, an upper layer wire cross arm, middle layer wire cross arms and a lower layer auxiliary cross arm. The top layer ground wire cross arm is arranged at the top of the tower body and is in a V shape, and two lateral cross arms are distributed in the direction perpendicular to line directions on the two sides. The upper layer wire cross arm is arranged below the top layer ground wire cross arm and is in a V shape, two lateral cross arms are distributed in the direction perpendicular to line directions on the two sides, strain suspension mid-phase wires are fixed to the tip portions of the cross arms, and cable terminals shaped like the Chinese character 'bo' are fixed to the tip portions of the cross arms. The angle tower has the advantages that the angle tower for charging, breaking and leading-down of the single-circuit overhead transmission line cable is suitable for the corner of an overhead transmission line, can serve as an angle tower with the rotation angle of 45-90 degrees, cable charging and breaking are achieved only with one single-circuit cable charging and breaking strain tower, construction cost is low, occupied area is small, and an original line distribution mode is not changed and suitable for construction of tangent towers nearby.
