Abstract
The utility model relates to a cable and in particular relates to a 66-500kV anti-ant anti-static environment-friendly cable. The 66-500kV anti-ant anti-static environment-friendly cable comprises a conductor and an insulation layer; a wrapping tape is sleeved out of the insulation layer; a sheath is arranged out of the wrapping tape; the cable is characterized in that the sheath consists of an inner sheath and an outer sheath; a conductive-type graphite layer is coated out of the outer sheath; and a metal sleeve or metal shield layer is arranged between the inner sheath and the wrapping tape. The cable has the following characteristics of capability of effectively avoiding white ant damage, environment friendliness, long service life, anti-static performance, simple structure, and the like.
Description
Technical field
The utility model relates to a kind of cable, especially relates to the anti-ant antistatic environment-friendly cable of a kind of 66kV ~ 500kV.
Background technology
As everyone knows, China South China termite causes disaster, and termite damages and happens occasionally being embedded in underground cable, brings immeasurable loss to electric power system.The cable that has termite area major part to select has all been taked anti-ant measure, prevents the ant medicament inner the adding at cable jacket that is:, plays the effect of walking quickly and keeping away and killing, and prevents termite destruction cable line.But can have defective and deficiency like this, mainly contain following 3 points: 1, the cable jacket the inside adds medicament, destroys cable although can prevent termite, and the toxicity of medicament can cause very severe contamination to environment, does not meet environmental requirement; 2, oversheath adds medicament, and certain life span is arranged, and above behind the certain hour, medicament lost efficacy, and cable has just lost anti-ant function; 3, the high pressure, the ultrahigh voltage power cable that use are not at present considered the antistatic problem, cable can cause certain interference to peripheral cable especially control cables when operation, affect the signal transmission of other cables, the clutter that other cables send or harmonic energy also can affect the normal operation of high pressure, extra-high-tension cable.
Termite utilizes biting mouthparts to gnaw and bites cable, studies show that: the hardness of oversheath reaches Shao Shi D60 when above, can stop that just gnawing of termite bite; Termite can secrete formic acid (formal name used at school is formic acid) when biting object gnawing in addition, and formic acid has very strong corrosivity, and cable jacket must have excellent resistance to chemical corrosion.
Summary of the invention
The utility model mainly is the above-mentioned technical problem for the existing grade of prior art, and a kind of anti-ant antistatic environment-friendly cable of 66kV ~ 500kV that can effectively prevent termite destruction, environmental protection, long service life, antistatic is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of 66kV ~ 500kV prevents ant antistatic environment-friendly cable, comprise conductor and insulating barrier, insulating barrier is arranged with band outward, described band is provided with sheath outward, it is characterized in that described sheath is made of inner sheath and oversheath, described oversheath is laid with the conductivity type graphite linings outward, is provided with metallic sheath or metal screen layer between described inner sheath and the band.The utility model has changed the traditional form of sheath, sheath adopts the double-layer coextrusion pattern, rely on the hardness of sheath and the destruction that good resistance to chemical corrosion prevents termite, environmental protection, nuisanceless, and the life-span is long, and reliability is high, simultaneously in cable jacket surface-coated one deck conductivity type graphite linings, shield the inside and outside electric field of cable, avoided phase mutual interference between the cable line, improved the security reliability of cable line operation.
As preferably, described inner sheath adopts the high density polyethylene (HDPE) manufacturing, and described oversheath adopts the polyolefine material manufacturing.Inner sheath adopts high density polyethylene (HDPE), oversheath adopts the polyolefin jacket material of ultrahigh hardness, the polyolefin jacket material of this ultrahigh hardness has excellent resistance to chemical corrosion, and its hardness reached shore hardness D64, can stop that fully gnawing of termite bite.
As preferably, be provided with conductor shield between described conductor and the insulating barrier.Simple in structure, long service life.
As preferably, be provided with insulation screen between described insulating barrier and the band.
As preferably, described band is semi-conductive tape or semi-conductive buffer water-blocking band.
Therefore, the utlity model has and a kind ofly can effectively prevent termite destruction, environmental protection, long service life, antistatic, the characteristics such as simple in structure.
Description of drawings
Accompanying drawing 1 is a kind of structure cutaway view of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Shown in Figure of description 1, a kind of 66kV ~ 500kV prevents ant antistatic environment-friendly cable, comprise conductor 1 and insulating barrier 2, insulating barrier is arranged with band 6 outward, band is provided with sheath outward, sheath is made of inner sheath 3 and oversheath 4, is laid with conductivity type graphite linings 5 outside the oversheath 4, is provided with metallic sheath 7 between inner sheath and the band 6.Inner sheath adopts the high density polyethylene (HDPE) manufacturing, and described oversheath adopts the polyolefine material manufacturing.Be provided with conductor shield 8 between conductor 1 and the insulating barrier 2.Be provided with insulation screen 9 between insulating barrier 2 and the band 6.Band 6 is semi-conductive tape.
The utility model has changed the traditional form of sheath, sheath adopts the double-layer coextrusion pattern, inner sheath adopts high density polyethylene (HDPE), oversheath adopts the polyolefin jacket material of ultrahigh hardness, the polyolefin jacket material of this ultrahigh hardness has excellent resistance to chemical corrosion, and its hardness reached shore hardness D64, can stop that fully gnawing of termite bite.Rely on the hardness of sheath and the destruction that good resistance to chemical corrosion prevents termite, environmental protection, nuisanceless, and the life-span is long, reliability is high, simultaneously in cable jacket surface-coated one deck conductivity type graphite linings, shield the inside and outside electric field of cable, avoided phase mutual interference between the cable line, improved the security reliability of cable line operation.
Should be understood that this embodiment only is used for explanation the utility model and is not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
