Abstract
The invention discloses a buried wire which comprises a conductor. An insulating layer, a metal braiding layer, a shielding layer, a middle sheath layer, a hard protective layer, a flame retardant layer, a waterproof layer and an external sheath are sequentially sleeved on the conductor from the inside out. The cross sections of the conductor, the insulating layer, the metal braiding layer, the shielding layer and the middle sheath layer are round. The cross sections of the hard protective layer, the flame retardant layer, the waterproof layer and the external sheath are triangular. Fiber yarns are further filled between the middle sheath layer and the hard protective layer. The wire which has great endurance is not easily damaged.
Description
Technical field
The present invention relates to technical field of electric power, particularly relate to a kind of buried 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.
In addition on the one hand, generally include many electric conductor in existing cable, in use, be extruded bending, easily cause the contact of inner conductive conductor and friction and the wearing and tearing broken string that causes, therefore existing cable still defectiveness.And market sells 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 a kind of buried 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 a kind of buried electric wire, comprise conductor, described conductor is socketed with insulating barrier, wire sheathing, screen, middle tegillum, hard protection layer, flame-retardant layer, watertight composition and oversheath from inside to outside successively, the cross section of described conductor, described insulating barrier, described wire sheathing, described screen, described middle tegillum is circular, the cross section of described hard protection layer, described flame-retardant layer, described watertight composition and described oversheath is triangle, is also filled with silvalin between described middle tegillum and described hard protection layer.
Further, the cross section of described hard protection layer, described flame-retardant layer, described watertight composition and described 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 protection 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 the buried electric wire that the embodiment of the present invention provides.
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 the buried electric wire that the embodiment of the present invention provides, comprise conductor 1, conductor 1 is socketed with insulating barrier 2, wire sheathing 3, screen 4, middle tegillum 5, hard protection layer 6, flame-retardant layer 7, watertight composition 8 and oversheath 9 from inside to outside successively, the cross section of conductor 1, insulating barrier 2, wire sheathing 3, screen 4, middle tegillum 5 is circular, the cross section of hard protection layer 6, flame-retardant layer 7, watertight composition 8 and oversheath 9 is triangle, is also filled with silvalin between middle tegillum 5 and hard protection layer 6.
Further, the cross section of hard protection layer, flame-retardant layer, watertight composition and oversheath is equilateral triangle.
Further, insulating barrier is cross-linked polyolefin.
Further, screen is wire armoring.
Further, middle tegillum is olefines TPE insulating material.
Further, hard protection layer is galvanized steel strip.
Further, flame-retardant layer is muscovite or phlogopite.
Further, oversheath is the nylon material with self lubricity.
Wherein, screen can anti-electromagnetic interference; middle tegillum can cushion the extrusion abrasion between hard protection layer and screen; hard protection layer can support triangle shape structure; protection inside is not squeezed, and silvalin 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 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.
