The power cable comprises a conductor and an insulation layer sleeved on the outer side of the conductor, wherein an insulation shielding layer is sleeved on the insulation layer, and is characterized in that a polyethylene jacket is sleeved on the insulation shielding layer, a butyronitrile polyethylene jacket is sleeved on the outer layer of the polyethylene jacket, a metal shielding layer and an aluminum-plastic composite tape are arranged between the polyethylene jacket and the insulation shielding layer. The cable has the characteristics of strong antiseptic and greaseproof capability, long service life, and so on.
Description
Technical field
The utility model relates to a kind of cable, especially relates to a kind of resistance to chemical attack and grease proofing power cable.
Background technology
As everyone knows; the annual demand cable of present domestic oil plant, petrochemical plant, steel mill, colliery, sewage treatment plant and general chemical industry is increasing; in that the selection of cable is all needed to combine himself industry characteristic and purchases with using, mainly be that its employed cable touches aromatic solvent, acid-base class, oils through regular meeting.Because of a large amount of cables lacks acid and alkali-resistance, oils, aromatic solvent corrosive power preferably, the aging situation of cable insulation and sheath trend is more serious to making, and is annual because of the cable quality problem, very big to the normal influence on system operation of its industry.Common power cable sheath material changes its mechanical and physical performance and electrical property because of easily aging in having multiple solvent with corrosion immersional wetting such as aromatic solvent, soda acid chemicals, oils, and final influence is impaired to insulating.The used sheath material of cable industry does not possess and possesses acid and alkali-resistance, oils, aromatic solvent corrosive power preferably simultaneously at present.
Common electric power cable because of on material selection, can not find a kind of can anticorrosion again can be grease proofing sheath material so that cable is difficult to be suitable for have in the environment transmission line of the electric power of aromatic solvent, soda acid, oils.The cable that occurred chemical resistance on the industry, they extrude polythene material after adopting the vertical bag of plastic-aluminum band, are mainly used under soda acid, the aromatic compound environment, and can not play good fuel tolerance capability.And the direct employing acrylonitrile-butadiene rubber sheaths of common oil resistant cable great majority, but the acid and alkali-resistance of acrylonitrile-butadiene rubber, heat-proof aging, oxidability, electrical property are relatively poor.So develop particularly important that a kind of comprehensive cable with acid and alkali-resistance, anti-aromatic solvent, oil resistance just shows.
Summary of the invention
The utility model mainly be poor at the existing in prior technology antiseptic power, can't realize can anticorrosion again can be grease proofing, useful life is short etc. technical problem, provide a kind of antiseptic power strong, can anticorrosion again can be grease proofing, the resistance to chemical attack and the grease proofing power cable of long service life.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of resistance to chemical attack and grease proofing power cable, the insulating barrier that comprises conductor and be set in the conductor outside, the insulating barrier outside is arranged with insulation screen, it is characterized in that the described insulation screen outside is arranged with pe sheath, the pe sheath skin is arranged with the butyronitrile pe sheath, is provided with metal screen layer and aluminium-plastic tape between described pe sheath and the insulation screen.The construction of cable adopts vertical alclad plastic composite strip and crosslinked polyethylene tack coat to form the resistance to chemical attack layer, outermost layer extrudes the butyronitrile polyvinyl chloride composite materials and forms anti-oil reservoir structure, solved cable preferably and had use problem in aromatic solvent, soda acid, the oils environment at the same time.The anti-aromatic solvent of product, soda acid, oils performance are outstanding, electrical property and good mechanical property, advantage such as production cost is low.
As preferably, be provided with internal shield between described conductor and the insulating barrier.35kV and following resistance to chemical attack and grease proofing power cable, the structure of the utility model design is that the vertical outward alclad of insulated wire cores is moulded and extruded the crosslinked polyethylene tack coat behind the band and reach the acid-proof alkalization and learn the anti-aromatic solvent of burn into, outermost layer extrude have grease proofness, the butyronitrile polyvinyl chloride composite materials of composite attribute such as anti-aromatic solvent performance.The resistance to chemical attack of this uniqueness and grease proofing structure make cable can keep permanent operation in rugged environment.
As preferably, described aluminium-plastic tape is set in the metal screen layer outside.Simple in structure, easily manufactured, long service life.
Therefore, the utlity model has antiseptic power strong, can anticorrosion again can be grease proofing, characteristics such as long service life.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with 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 resistance to chemical attack and grease proofing power cable, the insulating barrier 2 that comprises conductor 1 and be set in the conductor outside, the insulating barrier outside is arranged with insulation screen 3, the insulation screen outside is arranged with pe sheath 4, the pe sheath skin is arranged with butyronitrile pe sheath 5, is provided with metal screen layer 6 and aluminium-plastic tape 7 between pe sheath and the insulation screen.Be provided with internal shield 8 between conductor and the insulating barrier.Aluminium-plastic tape 7 is set in metal screen layer 6 outsides.
In order to make cable have above performance, reach and extrude the crosslinked polyethylene tack coat after design adopts unique vertical alclad that requires to mould band, has excellent electric property, mechanical performance, heat aging property, the ability of environmental stress resistance and chemically-resistant corrosion, anti-aromatic solvent ability, outermost layer extrudes the butyronitrile polyvinyl chloride composite materials, because the butyronitrile polyvinyl chloride composite materials possesses the double grading of rubber and plastics, the grease proofness that not only has acrylonitrile-butadiene rubber, the energy of anti-the aromatic solvent, but also show the mechanical property of igelite excellence, electrical property, acid-proof alkaline and chemical stability preferably.The maximum innovation advantage of this type of cable is the characteristics according to different materials, design on the construction of cable, reached cable have can anticorrosion again can be grease proofing performance.Make cable in rugged environment, anti-aging keep permanent operation.
Cable anti-aging use principle is that the action principle of Corrosion Protection, anti-aromatic solvent and the chemical stability of utilization crosslinked polyethylene excellence and the aluminium compactness of passivation and aluminium lamination in acid-base solution overcomes corrosion and the infiltration to sheath of aromatic solvent, soda acid chemicals; Composite attributes such as the grease proofness of utilization butyronitrile polyvinyl chloride composite materials, anti-aromatic solvent performance.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.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 institute restricted portion equally.
