Abstract
The invention discloses a durable cable comprising a plurality of conductors and a central core produced by polyethylene foaming. Each conductor is wrapped in an insulated layer. The insulated layers wrapping the conductors surround the central core. A shielding layer wraps the insulated layers wrapping the conductors and the central core and is successively wrapped in a middle sheath layer, a waterproof layer, a fireproof high-temperature-resistant layer, and an outer sheath. Fiber yarns are filled between the insulated layers and the shielding layer.
Description
Technical field
The present invention relates to technical field of electric power, particularly relate to a kind of ruggedized 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 sometimes due to the short circuit of cable own, or, voltage excess load, or the reasons such as Exterior cable is on fire, cause cable on fire.After cable is on fire, quickly, make if the insulating barrier of cable outer layer parcel is grog, then itself is just inflammable, particularly when being energized, can cause serious fire at short notice, causing huge loss to the people and country for its burning rate.
What market was sold is all single core insulation jacketed cable, cannot meet this cable use run in water-fast, the chemically-resistant solvent of the oil resistant that should have, corrosion-resistant, acid and alkali-resistance, high-low temperature resistant, high pressure resistant property.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of ruggedized cable, and endurance 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 ruggedized cable, comprise some conductors, also comprise the central core be made up of polyethylene foam, described in every root, conductor is wrapped with insulating barrier, some insulating barriers being enclosed with conductor form a circle centered by described central core, the insulating barrier that screen is enclosed with conductor by some and described central core are all wrapped up, described screen is also enclosed with middle tegillum, watertight composition, fire-proof high-temperature resistant layer and oversheath outward successively, is also filled with silvalin between described insulating barrier and described screen.
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 fire-proof high-temperature resistant layer is phlogopite or muscovite.
Further, described oversheath is the nylon material with self lubricity.
Implement the present invention, there is following beneficial effect: oil resistant of the present invention is water-fast, chemically-resistant solvent, corrosion-resistant, acid and alkali-resistance, high-low temperature resistant, high pressure resistant, be not easy to damage, and resistance to bend(ing) and reelability better.
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 ruggedized 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 ruggedized cable provided by the invention, comprise some conductors 1, also comprise the central core 9 be made up of polyethylene foam, described in every root, conductor 1 is wrapped with insulating barrier 2, some insulating barriers 2 being enclosed with conductor 1 form a circle centered by described central core 9, the insulating barrier 2 that screen 3 is enclosed with conductor 1 by some and described central core 9 are all wrapped up, described screen 3 is outer is also enclosed with middle tegillum 4 successively, watertight composition 5, fire-proof high-temperature resistant layer 6 and oversheath 7, polyethylene foam 8 is also filled with between described insulating barrier 2 and described screen 3.
Wherein, described insulating barrier 2 is cross-linked polyolefin.Described screen 3 is wire armoring.Described middle tegillum 4 is olefines TPE insulating material.Described fire-proof high-temperature resistant layer 6 is phlogopite or muscovite.Described oversheath 7 is for having the nylon material of self lubricity.
Wherein, screen can anti-electromagnetic interference, and the central core of polyethylene foam can when being subject to high pressure, buffering squeeze pressure, and silvalin can reduce the wearing and tearing between insulating barrier and insulating barrier, therefore resistance to bend(ing) and reelability better.
Implement the present invention, there is following beneficial effect: oil resistant of the present invention is water-fast, chemically-resistant solvent, corrosion-resistant, acid and alkali-resistance, high-low temperature resistant, high pressure resistant, be not easy to damage, and resistance to bend(ing) and reelability better.
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.
