Abstract
The utility model relates to a polyvinyl chloride insulation steel strip armour polyvinyl chloride sheath power cable. The cable comprises at least one metal conductor. The each metal conductor is wrapped with a polyvinyl chloride insulation layer. The polyvinyl chloride insulation layer is wrapped with a polyvinyl chloride outer sheath layer. A tape wrapping layer is arranged between the polyvinyl chloride insulation layer and the polyvinyl chloride outer sheath layer. Steel-tape armouring is arranged between the tape wrapping layer and the polyvinyl chloride outer sheath layer. Insulating reliability of the cable is high and a flame-retardant effect is good. Damages to animals and plants can be prevented and a wear-resisting property is increased. The cable can be laid in an indoor place, in a tunnel, in a cable trench and can be buried underground and so on. The cable can bear a certain external mechanical force.
