The Industrial Status of Aluminum Magnet Wire Is Irreplaceable
As the name implies, Aluminum Magnet Wire(XINYU-ENAMELEDWIRE) http://www.xinyu-enameledwire.com/product/paper-covered-rectangular-copperaluminum-wire/ refers to the magnet wire with aluminum as the core. The magnet wire is used to manufacture insulated wires of coils or windings in electrical products. Also called winding wire. Aluminum magnet wire must meet the requirements of various applications and manufacturing processes. The former includes its shape, specification, ability to work at high temperature for a short time and a long time, as well as withstanding strong vibration in some occasions and centrifugal force at high speed, corona and breakdown resistance under high voltage, chemical corrosion resistance under special atmosphere, etc. The latter includes the requirements of stretching, bending and abrasion during winding and embedding, as well as swelling and erosion during impregnation and drying.
Aluminum magnet wire can be classified according to their basic composition, conductive wire core and electrically insulating layer. Generally, it is divided into aluminum core enameled wire, aluminum core enameled wire, aluminum core enameled wire and inorganic insulated wire according to the insulating material and manufacturing method used for the electrical insulating layer.
The earliest enameled wire of electromagnetic wire was oily enameled wire, made of tung oil, etc. The paint film has the poor abrasion resistance and cannot be directly used for manufacturing motor coils and windings, and a cotton yarn wrapping layer needs to be added when in use. Later, the polyvinyl formal enameled wire was invented. Its mechanical properties were greatly improved. It can be directly used in motor windings and is called high-strength enameled wire.
With the development of weak current technology, the self-adhesive enameled wire has appeared again, and coils with better integrity can be obtained without impregnation and baking. However, its mechanical strength is poor, and it can only be used in micro and special motors and small motors. In addition, in order to avoid the trouble of removing the paint film in advance during welding, a direct-welding enameled wire has been developed, the coating film of which can automatically fall off in a high-temperature tin lining tank, thus making the copper wire easy to weld.
Due to the increasingly wide application of enameled wires for aluminum magnet wire and the increasingly strict requirements, composite enameled wires have also been developed. The inner and outer paint films are made of different polymer materials, such as polyesterimide/polyamide-imide enameled wire. Therefore, aluminum magnet wire is increasingly applied to various related industries, and the industrial status of aluminum magnet wire is irreplaceable.
