Abstract
The utility model takes a copper clad aluminum conductor as an electromagnetic wire, the inner core of the electromagnetic wire is an aluminum wire which is covered with a layer of a cylinder shaped copper sheet, the electromagnetic wire also can belong to two or more copper clad aluminum conductors mutually in parallel or wound mutually, an insulation material layer is covered outside the electromagnetic wire. Or the insulation materials such as paper, insulating paint or glass fiber is clad around the conductor, to form the electromagnetic wire with the insulating layer. The copper clad aluminum electromagnetic wire has the same electrical conductivity with the same specification of copper core electromagnetic wire, the weight is light, the processing is easy, the operation is convenient, the copper can be saved above 80 percent, the product cost is effectively reduced, and the disadvantages that the easy-oxidation resistance of the conductor surface of an aluminum core electromagnetic wire is strong, and the corrosion prevention performance and the mechanical performance are poor are avoided.
Description
Technical field
It is electromagnetic wire with the copper clad aluminum conductor that the utility model relates to a kind of, is the electromagnetic wire of insulating material with polyvinyl chloride, polyethylene, crosslinked polyethylene or rubber.
Background technology
Present widely used copper core BLV is as electromagnetic wire with copper.China is the country of a copper resource shortage, and every year will be from a large amount of copper of external import.As the huge non-ferrous metal of a kind of demand, the copper valency on the international market is constantly soaring, and spot price rises violently 7.3 ten thousand yuan from 4.7 ten thousand yuan per ton of the beginning of the year from the beginning of this year.Economizing on copper and be not only the needs that enterprise reduces cost, also is the problem with national strategy meaning.
Aluminium is the non-ferrous metal that a kind of electric conductivity is only second to copper, and China has very abundant reserves and rich production and processing ability.In the lead of transmission of electricity usefulness, aluminium is used widely as the substitute of copper.Because the price of aluminium is far below copper, and the proportion of aluminium is littler than copper, the electromagnetic wire length that aluminium is made is more than three times of equivalent weight copper cash.But because the very easy oxidation in surface of aluminium, oxide layer is tougher, cause contact resistance big, and corrosion resistance and mechanical performance particularly intensity all are not so good as copper, and range of application is very limited.
Summary of the invention
It is the electromagnetic wire of electromagnetism core with the copper clad aluminum conductor that the utility model provides a kind of, is the electromagnetic wire of electromagnetism core to substitute with copper or aluminium.
The technical solution of the utility model is: copper-coated aluminum electromagnetic wire, it is characterized in that: electromagnetic wire is that heart is that aluminum steel is surrounded by one deck tubular copper sheet outward, form the electromagnetic wire of copper clad aluminum conductor, electromagnetic wire is surrounded by the insulation material layer of polyvinyl chloride or polyethylene or crosslinked polyethylene or rubber or oil-paper outward.Copper-coated aluminum electromagnetic wire of the present invention, the shape of its cross section can be circular oval or square; Make transformer in order to be more convenient for, copper-coated aluminum electromagnetic wire of the present invention, its electromagnetic wire is preferably the electromagnetic wire of rectangular cross section body, the electromagnetism core is that rectangular aluminum wire is surrounded by one deck rectangle tubular copper sheet outward, form the electromagnetism core of copper clad aluminum conductor, the outsourcing of electromagnetism core has the rectangle insulation material layer of polyvinyl chloride or polyethylene or crosslinked polyethylene or rubber or oil-paper.The technical solution of the utility model is: by traditional technology, conductor is processed into uninsulated circle or flat electromagnetic wire, again with paper, insulating varnish and (or) insulating material such as glass fiber is coated on around the conductor, forms the electromagnetic wire that has insulating barrier.
Copper-coated aluminum electromagnetic wire is the bimetallic composite conductor that coats one deck uniform thickness copper sheet on the aluminium bar with one heart, by tension and compression, can form the copper-clad aluminum conductor of all size after coating.Copper aluminium border forms stronger melts combine (metallurgical binding), makes lead become as a whole.
Copper-coated aluminum electromagnetic wire of the present utility model, copper cover aluminum have good conductivity, the intensity height of copper concurrently, and the density of aluminium is little, easily process plurality of advantages, self have again copper layer density evenly, characteristics such as high compactness, high extensibility.The utility model is compared with the prior art scheme, and it is as follows to have effect: one, compare with the copper electromagnetic wire of same specification, the conductivity of copper-coated aluminum electromagnetic wire is identical, and is in light weight, easily processing, easy to use, economize on copper more than 80%, effectively reduce the cost of product; Its two, than good conductivity, the intensity height of aluminum electromagnetic wire, contact resistance is little, good corrosion resistance has wide range of applications.
Description of drawings
Accompanying drawing has been represented copper-coated aluminum electromagnetic wire structural representation of the present utility model, wherein Fig. 1 is the cross-sectional structure schematic diagram of circular cross section copper-coated aluminum electromagnetic wire, and Fig. 2 is the perspective view of circular cross section copper-coated aluminum electromagnetic wire front end stripping of insulatin material layer.Fig. 3 is the cross-sectional structure schematic diagram of rectangular cross section copper-coated aluminum electromagnetic wire, and Fig. 4 is the perspective view of rectangular cross section copper-coated aluminum electromagnetic wire front end stripping of insulatin material layer.
Embodiment
Embodiment one, a kind of circular cross section copper-coated aluminum electromagnetic wire of the present utility model (seeing Fig. 1, Fig. 2), the heart circle of electromagnetic wire is aluminum steel 6 outer cylindric copper sheet 5 electromagnetic wires of one deck that are surrounded by, formed the lead of copper clad aluminum conductor, single electromagnetic wire is surrounded by the insulation material layer 4 of polyvinyl chloride or polyethylene or crosslinked polyethylene or rubber outward.The production technology of embodiment and ordinary copper core electric wire is identical, promptly by plastic extruding machine insulating material is extruded in around the copper clad aluminum conductor, again through supercooling, after-combustion, lettering and packing, becomes the copper-coated aluminum electromagnetic wire finished product.
Embodiment two, a kind of rectangular cross section copper-coated aluminum electromagnetic wire of the present utility model (seeing Fig. 3, Fig. 4), the heart 2 of electromagnetic wire is surrounded by one deck rectangle tubular copper sheet electromagnetic wire outward for rectangular aluminum wire, has formed the lead of copper clad aluminum conductor.With the copper clad aluminum conductor is raw material, by traditional technology, conductor is processed into uninsulated circle or flat electromagnetic wire, or with paper, insulating varnish and (or) insulating material 1 such as glass fiber is coated on around the conductor, forms the electromagnetic wire that has insulating barrier.Electromagnetic wire is wound in transformer coil and is immersed in the insulating oil, forms the insulation electromagnetic wire circle.It is identical, in light weight with the copper electromagnetic wire of same specification that copper-coated aluminum electromagnetic wire has conductivity, easily processing, easy to use, economize on copper more than 80%, effectively reduce product cost, avoided the easy oxidation of aluminum electromagnetic wire conductive surface again, contact resistance is big, the shortcoming of corrosion resistance and bad mechanical property.
