The invention relates to an energy-saving cable bridge which comprises connecting arms, first transverse pipes, a movable air circulation mechanism and a traction mechanism, the connecting arms are of square tubular structures, the number of the connecting arms is two, the connecting arms are parallel, the first transverse pipes are arranged at intervals in the length direction of the connecting arms, and the first transverse pipes are used for bearing a cable; a first through hole corresponding to a cable is formed in the upper portion of the first transverse pipe, the connecting arm is provided with a second through hole communicated with the end of the first transverse pipe, the connecting arm is further provided with a long-strip-shaped third through hole, and the third through hole and the second through hole are arranged in a staggered mode in the length direction of the connecting arm. The movable air circulation mechanism comprises a shell, a fan assembly and an air exhaust square pipe, and the traction mechanism is used for pulling the shell to move relative to the connecting arm. The heat dissipation effect of the cable can be improved, so that the current transmission loss of the cable is reduced, and an energy-saving effect is achieved.
