Power cable outer sheath defect detection equipment and detection method

The invention discloses power cable outer sheath defect detection equipment and a detection method, and relates to the technical field of power cable detection.The power cable outer sheath defect detection equipment comprises an operation table, the side wall of the operation table is fixedly connected with a U-shaped frame, the top end of the operation table is fixedly connected with two symmetrical vertical plates, and the outer walls of the vertical plates are fixedly connected with motors; rainwater or sewage and impurities on the surface of the outer sheath of the power cable are wiped cleanly through the wiping sponge, then the surface of the outer sheath of the power cable is brushed with contaminant powder through the powder brush fixed in the wiping ring, and when the surface of the outer sheath of the power cable has defects and the power cable passes through equipment, the contaminant powder is brushed into the wiping ring. The powder on the transparent film from the surface of the outer sheath of
