Embodiment Construction

[0008] Referring to the accompanying drawings, the aluminum core 1 is coated with a copper layer 2, and the outer surface of the copper layer 2 is coated with a layer of nano mica insulating varnish 3.

[0009] Due to the "skin effect" of the conductor—that is, the high-frequency current is mainly concentrated on the surface layer of the conductor, that is, the copper layer 2 for transmission. Although the DC resistivity of copper-clad aluminum is equivalent to 1.55 times that of copper, the AC resistivity acting on the operation of motors and transformers tends to be close to that of pure copper wire. Especially in high-frequency signal transmission, due to the skin effect of the conductor, the difference in performance is very small. Therefore, the copper-clad aluminum nano-mica enameled wire can not only realize the purpose of replacing copper with aluminum, reduce costs, and improve benefits; Bimetal is used as the conductor core, which has the advantages of good conducti...

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 [0001] The invention relates to a copper-clad aluminum bimetal wire, in particular to a copper-clad aluminum nano mica enameled wire. Background technique [0002] At present, people have developed a variety of composite wires to solve the problems of expensive copper wires, poor conductivity of aluminum wires, and increasingly scarce copper resources, such as copper-clad steel and copper-clad aluminum composite wires. For example, the Chinese patent whose notification number is "CN 2348466Y" discloses a copper-clad aluminum bimetallic conductor, the main structure of which is composed of an aluminum core and a copper layer coated on the aluminum core. It replaces high-priced copper metal with most low-priced aluminum metal, saving a lot of copper resources. In terms of transmission, due to the skin effect of the conductor, there is little difference in performance. However, the disadvantages of copper-clad aluminum bimetallic conductors are that they have a...
