The invention discloses a four-loop cable breaking strain tower which comprises a tower body; a ground wire cross arm on a top layer, an upper double-loop wire cross arm, a lower double-loop wire cross arm and an auxiliary cross arm on a bottom layer, wherein the ground wire cross arm on the top layer and the upper double-loop wire cross arm are arranged in a direction perpendicular to a circuit direction from the side surface of the tower body, and are consistent in the vertical direction; and the lower double-loop wire cross arm and the auxiliary cross arm on the bottom layer are arranged in the shape of T, and are consistent in the vertical direction, and an included angle between two adjacent cross arms is 90 degrees. Each tip part of the lower double-loop wire cross arm is connected with a cable suspension bracket; and each cable suspension bracket is connected with a cable downward-leading terminal which is in the shape of Chinese character bu. The tower is used on a corner of an overhead power transmission line, can be used as an angle tower with a rotation angle ranging from 45 degrees to 90 degrees, can be used for four-loop single-side or double-side on-off, is suitable for being constructed near a linear tower; and compared with an existing scheme, a base rod tower is omitted, construction cost is reduced and floor space is reduced.
