Abstract
The utility model discloses a computer electric cable used in automatic facility construction of a hydraulic power plant, which comprises a conductor and a total shielding layer. The computer electric cable is characterized in that the conductor is coated with an insulation layer on the outer wall and positioned into an infilling body; a water blocking tape is wrapped outside the infilling body so as to form a wrapping layer; a plastic-aluminum composite belt is vertically wrapped and then an outer layer of weaving screen is wrapped outside the wrapping layer; and an outer layer of sheath is extruded outside the total shielding layer. The utility model has the advantages of simple structure, good mechanical property, low cost, good interference free performance, mildew-proof property, termite protection and waterproof effects, strong capability of environment adaptability and reliable operation.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of Automation of Hydropower Station Facilities Construction computer cable.
Background technology
The Automation of Hydropower Station Facilities Construction adopts copper conductor, screen, low-smoke halogen-free polyolefin sheath with used cable more at present, this just cause cable expensive and anti-interference, the radiation hardness degree is low, especially Automation of Hydropower Station Facilities Construction with computer with the conductor of cable account for total cost more than 75% and waterproof, mildew-resistant require higher, any problem can not occur, and existing single-layer shield common material protective-cover type structure can't meet the demands.
Summary of the invention
It is expensive and its screening ability is not good, waterproof, mildew-resistant, problem such as termite-proof with cable with computer in order to solve present Automation of Hydropower Station Facilities Construction that the purpose of this utility model is exactly, provide a kind of have simple in structure, easy to use, cable cost be can effectively reduce and cable antijamming capability, waterproof, mildew-resistant, termite-proof Automation of Hydropower Station Facilities Construction computer cable improved.
For achieving the above object, the utility model adopts following technical scheme:
A kind of Automation of Hydropower Station Facilities Construction computer cable, it comprises conductor, total screen, it is characterized in that the outer wall wrap insulate layer of conductor and place in the obturator, the outer wrapped waterstop of obturator forms lapping layer, the outer more total screen of outer braid shielding formation of wrapping up in behind the vertical outward alclad plastic composite strip of lapping layer, total screen extrudes outer protective sleeve outward.
Described outer braid shielding is the shielding of copper wire or tinned copper wire or the braiding of aluminium in copper magnesium silk.Total shielding is the combination shielding of using aluminium-plastic tape and copper wire or tinned copper wire or aluminium in copper magnesium silk formation, preferably shields with the combination that the tinned copper wire braiding constitutes.
The utility model Automation of Hydropower Station Facilities Construction can adopt many heterogeneous double-level-metals to draw the conductor that forms with computer cable; Preferred internal layer is an aluminium conductor, and skin is a copper conductor, and the outer preferred employing polytetrafluoroethylene of copper conductor is the insulating barrier of material, has better insulation property.Two-layer conductor organically in conjunction with the electric energy that guarantees cable and effective transmission of small-signal, has been saved the copper resource, has been reduced cost.The obturator at insulating barrier place adopts waterproofing rope to fill, and the wrapped obturator of waterstop adds the aluminum plastic composite belt longitudinal bag and constitutes watertight composition, has guaranteed the water-proof function of cable.
Described outer protective sleeve adopts mildew-resistant, termite-proof protective cover material, and the protective action of the existing sheath in the past of this sheath has strengthened the mildew-resistant of cable, termite-proof performance again, makes the environment for use of cable more extensive.Described mildew-resistant, termite-proof protective cover material is commercially available gets.
Its total screen adopts the combination shielding, that is: the aluminium-plastic tape shielding adds copper wire or tinned copper wire or aluminium in copper magnesium silk braiding combination shielding, combination shielding has changed the single-layer shield of prior cable, and the antijamming capability to external world that the shielding of double-deck different materials has strengthened cable has also increased the mechanical performance of cable.In addition, aluminum plastic composite belt longitudinal holds outside the covering, is thermoplastic welding, no seam.Aluminium-plastic tape is wrapped up in the outer braid shielding outward, and the shielding properties of existing metal tape has water resistance again, contains again to mould the band mechanical stress, makes total screen firm more, reliable.
Preferred tinned copper wire braiding makes the screen of cable have corrosion-resistant, oxidation resistant characteristic, increases the useful life of cable shield, makes the performance shielding action that screen more can be permanent.
The beneficial effects of the utility model are: simple in structure, and good mechanical property, cost is low, good in anti-interference performance, mildew-resistant, termite-proof, good water-proof effect, accommodative ability of environment is strong, reliable operation.
Description of drawings
