The invention provides equipment for coating a cable. The equipment for coating the cable comprises a rack, a pay-off device, an impurity removal device, a guide device, a coating device and a take-up device, wherein the pay-off device, the impurity removal device, the guide device, the coating device and the take-up device all are arranged on the rack; the rack comprises a bracket and a bottom plate; the bracket is set into a portal structure and is vertically arranged across the bottom plate; one side of the upper surface of the bottom plate is sequentially provided with the pay-off device, the impurity removal device and the guide device; the pay-off device, the impurity removal device and the guide device all are arranged at the lower part of the bracket; the coating device is horizontally arranged across two vertical arms of the bracket; and the take-up device is arranged on a beam of the bracket. By adopting a coating machine, the equipment is simple in structure, and is capable of effectively smoothing and cleaning the surface of the to-be-processed cable, so that a shielding layer is clung to the surface of the cable, and good coating quality of the cable is ensured.
