Abstract
This invention discloses a kind of copper wrapped aluminium nano mica emamelled wire, including aluminium core (1) and the copper layer (2) covered over the aluminium core (1), a layer of nana mica insulation paint is coated over the outer surface of the said copper layer (2). The invention is a kind of aluminium- in- copper nano mica enamelled wire with thin insulation layer, strong performance of insulation, and with high performance of temperature-proof, pressure-proof, waterproof, oil-proof, corona proof,and simple structure, convenient fabrication as well as reliability.
Description
Technical field
The present invention relates to a kind of copper cover aluminum bimetallic conductor, particularly relate to a kind of aluminium-in-copper nano mica enamel-covered wire.
Background technology
At present, people have developed multiple compound wire, and problem that copper resource day by day deficient bad in order to the conduction valuable, aluminum conductor that solves copper conductor is as copper covered steel, copper-coated aluminum complex lead.Disclose a kind of copper cover aluminum bimetallic conductor as notification number for the Chinese patent of " CN 2348466Y ", its primary structure is to be made of aluminium core and the copper layer that is coated on the aluminium core.It has saved a large amount of copper resources with the copper metal of the alternative high price of aluminum metal of most low price, aspect transmission, because the kelvin effect of conductor then differs very little on the performance.But the shortcoming of copper cover aluminum bimetallic conductor is to have that insulating barrier is thicker, non-refractory, not high pressure resistant, poor performance such as waterproof, grease proofing, anti-corona.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of insulating barrier is thin, insulation property are strong, high temperature resistant, high pressure resistant and the high aluminium-in-copper nano mica enamel-covered wires of performance such as waterproof, grease proofing, anti-corona.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: be coated with the copper layer on the aluminium core, be coated with one deck nano mica insulating varnish at copper layer outer surface.
Adopt the aluminium-in-copper nano mica enamel-covered wire of technique scheme, because aluminium-in-copper nano mica enamel-covered wire is to make conductor with the copper cover aluminum bimetallic conductor, adopted high-tech nano material nano mica insulating varnish to make insulating varnish again, as the high-performance motor, the electrical equipment winding wire, has high-tech, new material characteristics cheaply, it substitutes the copper metal of high price with the aluminum metal of most low price, saved a large amount of copper resources, in addition, the density of copper cover aluminum is 1/2.45 of fine copper, thereby can alleviate the weight of wire rod unit length significantly, more help China's motor, transformer, so client unit such as IT information industry conveniently uses and reduces cost.Its adopts high-tech nano mica insulating varnish to make insulating material, has ultra-thin, superpower, high temperature resistant, the high pressure resistant and waterproof of insulating barrier, the contour performance advantage of grease proofing, anti-corona.
In sum, the present invention is that a kind of insulating barrier is thin, insulation property are strong, high temperature resistant, high pressure resistant and performance aluminium-in-copper nano mica enamel-covered wires high and simple in structure, easily manufactured, dependable performance such as waterproof, grease proofing, anti-corona.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Referring to accompanying drawing, on aluminium core 1, be coated with copper layer 2, be coated with one deck nano mica insulating varnish 3 at copper layer 2 outer surface.
Because " kelvin effect " of conductor---promptly: it is 2 transmission of copper layer that high-frequency current mainly concentrates on the surface of conductors layer.Though the dc resistivity of copper cover aluminum is equivalent to 1.55 times of copper, acts on motor, the operating AC resistance rate of transformer and then level off to pure copper wire.Particularly aspect the high-frequency signal transmission, because the kelvin effect of conductor then differs very little on the performance.Therefore, aluminium-in-copper nano mica enamel-covered wire not only can be realized with aluminium reducing cost the purpose of increasing the benefit for copper; Can bring into play the high-tech nanometer technology again and promote product hierarchy, and promote the advantage of model change; The present invention adopts the copper cover aluminum bimetallic to make conductor thread core, has advantages such as the density of good conductivity, intensity height and aluminium of copper is little, in light weight concurrently; Adopt high-tech nano mica insulating varnish 3 to make insulating material again, have that insulating barrier is ultra-thin, superpower, adhesive force is good and high temperature resistant, high pressure resistant, waterproof, the contour quality parameter of grease proofing, anti-corona; Both can be used as high-performance motor, electrical equipment winding wire, and also can be used as the high-frequency signal transmission aspect and make to compile the switch coil winding wire.
