The invention provides a waste cable recovery system and belongs to the technical field of waste cable reuse. The system includes frame, pay-off roll, straightening device, cutting device, cop core winding roller, two cooling devices, two cutting devices and crushing device. A let-out roller, a straightening device, a cutting device and a cop core winding roller are arranged in sequence from one end of that frame, two cooling device and two cutting devices are arranged between the cutting device and the cop core winding roller and are symmetrically arranged on both sides of the frame, the cooling device is close to the frame, and the cutting device is far away from the frame. The invention provides a waste cable recovery system, by carrying out straightening first, and Cutting, Cut off thecable sheath after cooling, the cable sheath after the cutting-off falls into the lower crushing device for crushing, copper core is wound on the copper core winding roller along a straight line, after straightening the cable sheath, adhesion and incessant cutting of the cable sheath can be avoided, thereby avoiding scratching the copper core, the cable sheath is cut off after cooling, and is easy to cut and crushing.
