Description
Technical field
A kind of lv power cable is the utility model is related to, belongs to field of cable technology.
Background technology
Cable is typically by several or the cable of similar rope that several groups of wires [every group at least two] are twisted, every group
Mutually insulated between wire, and be often twisted into around a center, whole outside is surrounded by the coating of high-insulation.It is erected at more
In the air or mounted in underground, the bottom, for telecommunication or power Transmission.1832, tsarist Russia's army officers were permitted woods lattice and are buried telegraphy line
Each other with, with being placed in glass tube, here it is an earliest in the world underground after rubber-covered between underground, six conductors
Cable.Its water proofing property of existing lv power cable is poor, and loses time, and cost is high, and the filler utilized is more, cause core with
Gap between core is big.
Utility model content
In view of the above-mentioned problems, the technical problems to be solved in the utility model is to provide a kind of lv power cable.
A kind of lv power cable of the present utility model, it include crosslinked polyetylene insulated body, sector conductor, non-woven fabrics around
Band, polyethylene inner sheath, galvanized steel strip, polyvinyl chloride oversheath；The outer surface of four sector conductors is provided with friendship
Join polyethylene insulator, four sector conductors form a round, and the lateral wall of four sector conductors is provided with
Non-woven fabrics twining package tape, the outer surface of the non-woven fabrics twining package tape are provided with polyethylene inner sheath, the polyethylene inner sheath it is outer
Side is provided with galvanized steel strip, and the outer surface of the galvanized steel strip is provided with polyvinyl chloride oversheath.
Compared with prior art, the beneficial effects of the utility model are：In the case where cross-sectional area of conductor is constant, change conductor
Shape, the cable core being combined into stranding, gap is small between core and core, reduces material filling, substantially reduces the outside diameter of cable,
To improving production efficiency, save production cost and serve obvious effect；The waterproof of cable is added using polyethylene inner sheath
Performance, improve service life.
Brief description of the drawings
For ease of explanation, the utility model is described in detail by following specific implementations and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
In figure：The crosslinked polyetylene insulated bodies of 1-；2- sector conductors；3- non-woven fabrics twining package tapes；4- polyethylene inner sheaths；5- is plated
Zinc steel band；6- polyvinyl chloride oversheaths.
Embodiment
To make the purpose of this utility model, technical scheme and advantage of greater clarity, below by what is shown in accompanying drawing
Specific embodiment describes the utility model.However, it should be understood that these descriptions are merely illustrative, and it is not intended to limit this reality
With new scope.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily mixing
Confuse concept of the present utility model.
As shown in figure 1, present embodiment uses following technical scheme：It includes crosslinked polyetylene insulated body 1, sector
Conductor 2, non-woven fabrics twining package tape 3, polyethylene inner sheath 4, galvanized steel strip 5, polyvinyl chloride oversheath 6；Four sector conductors 2
Outer surface be provided with crosslinked polyetylene insulated body 1, four sector conductors 2 form a round, four fans
The lateral wall of shape conductor 2 is provided with non-woven fabrics twining package tape 3, and the outer surface of the non-woven fabrics twining package tape 3, which is provided with polyethylene, to be protected
Set 4, the outside of the polyethylene inner sheath 4 is provided with galvanized steel strip 5, and the outer surface of the galvanized steel strip 5 is provided with polychlorostyrene second
Alkene oversheath 6.
The operation principle of present embodiment is：The hard pressure conductor of the class of cable conductor two, after circular die is crossed, is used
Special-shaped pressing mold is suppressed conductor, obtains sector conductor, crosslinked polyetylene insulated, more fan-shaped insulated wire cores are extruded outside conductor
Combined during stranding using back twist, be combined into circular cable core.Wrapped non-woven fabrics twining package tape outside cable core, non-woven fabrics are extruded in polyethylene and protected outside
Cover, overlapping wrapped metal armor layers outside interior shield, finally extrude polyvinyl chloride oversheath.The cable feature is constant in cross-sectional area of conductor
In the case of, change conductor shape, the cable core being combined into stranding, gap is small between core and core, reduces material filling, greatly
The outside diameter of cable is reduced greatly, to improving production efficiency, production cost is saved and serves obvious effect.Using polyethylene inner sheath
The water resistance of cable is added, improves service life.
The standardized element that the utility model uses can commercially, shaped piece according to specification and accompanying drawing
Record can carry out customized, the specific connected mode of each part is using bolt ripe in the prior art, rivet, weldering
The conventional meanses such as connect, machinery, part and equipment are using in the prior art, conventional model, plus circuit connection using existing
Conventional connected mode, will not be described in detail herein in technology.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It is appreciated that other embodiment.
