Abstract
The utility model relates to a polyvinyl chloride insulation power cable. The polyvinyl chloride insulation power cable comprises a metal conductor, a mica tape layer, a first polyvinyl chloride insulation layer, a shielding layer and a second polyvinyl chloride insulation layer, wherein the mica tape layer is wound on the outer surface of the metal conductor; and the metal conductor, the mica tape layer, the first polyvinyl chloride insulation layer, the shielding layer and the second polyvinyl chloride insulation layer are sequentially coated from inside to outside. The polyvinyl chloride insulation power cable disclosed by the utility model has many advantages of being high in structure strength, not easy to age, good in shielding property, not easy to combust, and the like.
Description
Technical field
The utility model relates to a kind of power cable, is specifically related to a kind of PVC insulated power cable, belongs to technical field of electric wires and cables.
Background technology
At present, the electric wire that we use is normally at wire outer cladding one deck plastic layer.Yet, because the structural strength of plastics is poor, easily damaged and aging, therefore existing electric wire is shorter useful life.
Simultaneously, the electric wire of prior art also exists shielding poor, and the easy defect such as burning has limited the application of electric wire.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved PVC insulated power cable that has, to overcome described defect of the prior art.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of structural strength high, be difficult for aging, the PVC insulated power cable that shielding is good and nonflammable.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of PVC insulated power cable, and it comprises metallic conductor, mica belt, the first polyvinyl chloride insulation layer, screen and the second polyvinyl chloride insulation layer; Wherein, described mica belt is wound in the outer surface of metallic conductor; Described metallic conductor, mica belt, the first polyvinyl chloride insulation layer, screen, the second polyvinyl chloride insulation layer from-inner-to-outer coat successively.
PVC insulated power cable of the present utility model further is set to: described metallic conductor is specially the metallic conductor of copper material, and its cross section is rounded.
PVC insulated power cable of the present utility model further is set to: described screen is specially the screen formed by the thin copper wire braiding.
Compared with prior art, the utlity model has following beneficial effect: PVC insulated power cable of the present utility model have structural strength high, be difficult for aging, shielding good and the plurality of advantages such as nonflammable.
The accompanying drawing explanation
Fig. 1 is the cutaway view of PVC insulated power cable of the present utility model.
Embodiment
Refer to shown in Figure of description 1, the utility model is a kind of PVC insulated power cable, and it is comprised of several parts such as metallic conductor 1, mica belt 2, the first polyvinyl chloride insulation layer 3, screen 4 and the second polyvinyl chloride insulation layers 5.
Wherein, described metallic conductor 1 is specially the metallic conductor 1 of copper material, and its cross section is rounded.Described metallic conductor 1, mica belt 2, the first polyvinyl chloride insulation layer 3, screen 4, the second polyvinyl chloride insulation layer 5 from-inner-to-outer coat successively.
Described mica belt 3 is wound in the outer surface of metallic conductor 1, and this mica belt 3 has good fire resistance.
Described the first polyvinyl chloride insulation layer 3, the second polyvinyl chloride insulation layer 5 can make the structural strength of this power cable increase, and are difficult for aging.
