The invention discloses a self-balancing arc cable saddle, which comprises a tower cable saddle longitudinal beam, wherein at least three cable saddle wheel devices are arranged on a vertical plane of the cable saddle longitudinal beam from low to high at intervals; a first cable saddle wheel device is vertical to a tower top main beam; a first acute included angle is formed in a horizontal planebetween the last cable saddle wheel device and the first cable saddle wheel device; the first cable saddle wheel device is horizontally arranged in the vertical plane; the last cable saddle wheel device is arranged on the vertical plane in an inclined mode and has a first inclination angle; and the inclination direction of the last cable saddle wheel device inclines downwards along the direction of the acute included angle formed in the horizontal plane between the last cable saddle wheel device and the first cable saddle wheel device. A main cable of the self-balancing arc cable saddle realizes horizontal turning, and the component force generated by the inclination of the cable saddle counteracts the horizontal force generated by the horizontal turning of the main cable to realize self balancing, thereby making cable saddle wheels in a pure compression state and greatly reducing the abrasion of a rope system. The self-balancing arc cable saddle adopts at least three rows of the cable saddle wheels from front to back, has a simplified structure system, and reduces the manufacturing difficulty degree and the dead weight.
