The present invention relates to a cable sheathing removal device, and more particularly, to a cable sheathing device applicable to a processed insulated three-core cable.

In general, various wire cables installed during communication and electrical construction must be connected to various devices after removing the sheath of the end of the cable at the final stage.

A cable with a general single-core structure has a neutral wire inside the outer sheath, so that the neutral layer can protect the insulation layer and the semi-conductive layer from the blade when the outer sheath is removed. As the copper mylar tape must also be removed when the outer skin is removed, precise force control is difficult, resulting in frequent work mistakes. In addition, the neutral wire thickness of a general cable is 12mm (based on 400㎟), whereas the neutral wire thickness of a processed insulated 3-core cable is up to 0.35mm, which is vulnerable to sharp blades.

The background art of the present invention is disclosed in Republic of Korea Patent Registration No. 10-1379028 (registered on March 21, 2014, title of the invention: cable sheathing peeling device).
