Abstract
The invention discloses a pressure-resistant electric wire. The pressure-resistant electric wire comprises a conductor, an insulating layer, a solid protection layer, an intermediate lining layer, a shielding layer, a fire-retardant layer, a water-resistant layer and an outer protection sleeve the conductor sequentially from inside to outside, a cross section of each of the conductor and the insulating layer is shaped circularly, a cross section of each of the solid protection layer, the intermediate layer, the shielding layer, the fire-retardant layer, the water-resistant layer and the outer protection sleeve is shaped in an equilateral triangle, and a space between the insulating layer and the solid protection layer is filled with polyethylene foaming. The pressure-resistant electric wire is less prone to damage.
Description
Technical field
The present invention relates to technical field of electric power, particularly relate to a kind of resistance to compression electric wire.
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 and anti-electromagnetic interference characteristic.
Summary of the invention
Technical problem to be solved by this invention is, provides resistance to compression electric wire, and endurance is comparatively strong, is not easy to damage.
In order to solve the problems of the technologies described above; the invention provides resistance to compression electric wire; comprise conductor; described conductor is socketed with insulating barrier, hard protective layer, middle tegillum, screen, flame-retardant layer, watertight composition and oversheath from inside to outside successively; the cross section of described conductor, described insulating barrier is circular; the cross section of described hard protective layer, middle tegillum, screen, flame-retardant layer, watertight composition and oversheath is triangle, is also filled with polyethylene foam between described insulating barrier and described hard protective layer.
Further, the cross section of described hard protective layer, middle tegillum, screen, flame-retardant layer, watertight composition and oversheath is equilateral triangle.
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 flame-retardant layer is muscovite or phlogopite.
Further, described oversheath is the nylon material with self lubricity.
Implement the present invention, there is following beneficial effect: the present invention is wear-resisting withstand voltage, oil resistant be water-fast, chemically-resistant solvent, corrosion-resistant, acid and alkali-resistance, high pressure resistant, anti-electromagnetic interference, be not easy 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 compression electric wire 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 compression electric wire provided by the invention; comprise conductor 1; described conductor 2 is socketed with insulating barrier 2, hard protective layer 3, middle tegillum 4, screen 5, flame-retardant layer 6, watertight composition 7 and oversheath 8 from inside to outside successively; the cross section of described conductor 1, described insulating barrier 2 is circular; the cross section of hard protective layer 3, middle tegillum 4, screen 5, flame-retardant layer 6, watertight composition 7 and oversheath 8 is triangle, is also filled with polyethylene foam between described insulating barrier 2 and described hard protective layer 3.
Further, the cross section of hard protective layer 3, middle tegillum 4, screen 5, flame-retardant layer 6, watertight composition 7 and oversheath 8 is equilateral triangle.
Further, insulating barrier 2 is cross-linked polyolefin.
Further, hard protective layer 3 is galvanized steel strip.
Further, middle tegillum 4 is olefines TPE insulating material.
Further, screen 5 is wire armoring.
Further, flame-retardant layer 6 is muscovite or phlogopite.
