Abstract
The invention discloses a reinforced polyvinyl chloride insulated cable, which comprises a cable core, a reinforced protective sleeve layer and a protective sleeve layer, wherein the inside of the cable core is formed by stranded copper wires; a polyvinyl chloride insulating layer is arranged at the outer side of the cable core; a reinforced protective sleeve layer is arranged outside the polyvinyl chloride insulating layer; the inner side surface of the reinforced protective sleeve layer coats the polyvinyl chloride insulating layer; a plurality of protective convex glue points are formed in the outer side surface of the reinforced protective sleeve layer; the protective sleeve layer is arranged at the outer side of the reinforced protective sleeve layer; and the part between the protective sleeve layer and the reinforced protective sleeve layer is filled with elastic rubber particles. In the manner, the strength of the polyvinyl chloride cable can be improved; and a cable body can be protected by buffering pressure when extruded by external force.
