The technical solution adopted for the present invention to solve the technical problems is: a kind of polyvinyl chloride insulation steel-tape armouring pe sheath power cable, it comprises at least one metallic conductor, each metallic conductor is coated with the polyvinyl chloride insulation layer, the polyvinyl chloride insulation layer is coated with the polyethylene external sheath layer, be provided with belting layer between polyvinyl chloride insulation layer and the polyethylene external sheath layer, be provided with steel-tape armouring between belting layer and the polyethylene external sheath layer.
Further: the cross section of each metallic conductor is circle or fan-like pattern.
Further: each metallic conductor is copper core or aluminium core.
Further: metallic conductor is 2 or 3 or 4 or 3+1 or 5 or 4+1 or 3+2.
Further: be equipped with packed layer between the outer polyvinyl chloride insulation layer that coats of belting layer and each metallic conductor and between the outer polyvinyl chloride insulation layer that coats of each metallic conductor.
Beneficial effect of the present invention: each metallic conductor is coated with the polyvinyl chloride insulation layer in the cable of the present invention, and under rated voltage 0.6/1kV condition of power supply, the insulating reliability of polyvinyl chloride insulation layer is big; The polyvinyl chloride insulation layer is coated with the polyethylene external sheath layer, the good flame retardation effect of polyethylene external sheath layer; Be provided with steel-tape armouring between belting layer and the polyethylene external sheath layer, steel-tape armouring can prevent vegeto-animal destruction and strengthen anti-wear performance, and then prolonged useful life of cable, and be used in indoor, tunnel, the cable trough or buried-pipe laying etc., can bear certain mechanical external force.
