Abstract
The present invention discloses a voltage-resistant cable, comprising four conductors, wherein each conductor is wrapped with an insulating layer and a hard protecting layer from the inside out, the cross section of each hard protecting layer is in an equilateral triangle shape, the four hard protecting layers are tightly attached with each other to form another equilateral triangle, and the equilateral triangle consisting of the four hard protecting layers is wrapped with a middle coating layer, a shielding layer and an outer sheath successively, the cross sections of the middle coating layer, the shielding layer and the outer sheath are equilateral triangles. The voltage-resistant cable of the present invention is good in voltage resistant capacity and is not easy to damage.
Description
Technical field
The present invention relates to technical field of electric power, particularly relate to a kind of resistance to voltage cable.
Background technology
Electric transmission normally relies on cable to realize.Existing cable comprises two parts, electric conductor and insulating barrier, and electric conductor is used for transmitting electric power, and insulating barrier is wrapped in the outer surface of electric conductor, prevents electricity from leaking.But what market was sold is all single core insulation jacketed cable, this cable cannot be met in the characteristic using the high pressure resistant and anti-electromagnetic interference that should have in operation.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of resistance to voltage cable, and compression resistance is comparatively strong, is not easy to damage.
In order to solve the problems of the technologies described above; the invention provides a kind of resistance to voltage cable; comprise four conductors; conductor described in every root is enclosed with insulating barrier and hard protective layer from inside to outside; described hard protective layer cross section is equilateral triangle; four hard protective layers mutually fit tightly and are combined as another equilateral triangle; and the equilateral triangle be made up of four hard protective layers is enclosed with middle tegillum, screen and oversheath outward successively, the cross section of described middle tegillum, screen and oversheath is equilateral triangle.
Further, also polyethylene foam is filled with between described insulating barrier and described hard protective layer.
Further, described insulating barrier is cross-linked polyolefin.
Further, described screen is wire armoring.
Further, described middle tegillum is olefines TPE insulating material.
Further, described hard protective layer is galvanized steel strip.
Further, described oversheath is the nylon material with self lubricity.
Implement the present invention, there is following beneficial effect: wear-resisting withstand voltage, the anti-electromagnetic interference of the present invention, be not easy to damage.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the cross sectional representation of an embodiment of resistance to voltage cable provided by the invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the cross sectional representation of an embodiment of resistance to voltage cable provided by the invention; comprise four conductors 1; every root conductor 1 is enclosed with insulating barrier 2 and hard protective layer 3 from inside to outside; hard protective layer 3 cross section is equilateral triangle; four hard protective layers 3 mutually fit tightly and are combined as another equilateral triangle; and the equilateral triangle be made up of four hard protective layers 3 is enclosed with middle tegillum 4, screen 5 and oversheath 6 outward successively, the cross section of middle tegillum 4, screen 5 and oversheath 6 is equilateral triangle.
Wherein, also polyethylene foam is filled with between insulating barrier 2 and hard protective layer 3.
Wherein, insulating barrier 2 is cross-linked polyolefin.Hard protective layer 3 is galvanized steel strip.Middle tegillum 4 is olefines TPE insulating material.Screen 5 is wire armoring.Oversheath 6 is for having the nylon material of self lubricity.
Wherein, screen can anti-electromagnetic interference; middle tegillum can cushion the extrusion abrasion between hard protective layer and screen; hard protective layer can support triangle shape structure; protection inside is not squeezed, and polyethylene foam can when being subject to high pressure, buffering squeeze pressure; reduce wearing and tearing, which floor employing triangle outside can strengthen compressive resistance ability.
Implement the present invention, there is following beneficial effect: the present invention wear-resisting withstand voltage, anti-pressure ability is strong, anti-electromagnetic interference, be not easy damage.
It should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or device and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or device.When not more restrictions, the key element limited by statement " comprising ... ", and be not precluded within process, method, article or the device comprising this key element and also there is other identical element.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
