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, and the magnet wire is used to manufacture insulated wires of coils or windings in electrical products. Also called winding wire. Magnet wires 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 wires can be classified according to their basic composition, conductive wire core and electrically insulating layer. Generally, it is divided into aluminum enameled wire, aluminum wrapped wire, aluminum enameled wrapped wire and inorganic insulated wire according to the insulating material and manufacturing method used for the electrically insulating layer.
Enameled wire of aluminum magnet wire: coat the conductor with corresponding paint solution, and then volatilize the solvent, solidify the paint film and cool it. Enameled wires can be divided into polyester enameled wires, polyester-imide enameled wires, polyamide-imide enameled wires, polyimide enameled wires, polyester-imide/polyamide-imide enameled wires, corona-resistant enameled wires, as well as oil paints, acetal paints, polyurethane enameled wires, etc. according to the insulation paint used. Sometimes it is also classified according to the particularity of its application, such as self-adhesive enameled wire, cryogen-resistant enameled wire, etc.
The winding of magnet wire: An Important Variety of Winding Wire. Early use of cotton yarn and silk, known as yarn and silk wrap, was used in electrical machines and appliances. Due to the large insulation thickness and low heat resistance, most of them have been replaced by enameled wires. At present, it is only used as a high-frequency winding wire. In large and medium-sized winding wires, when the heat resistance level is high and the mechanical strength is high, glass wire wrapping wire is also adopted, and appropriate adhesive paint is matched during manufacturing.
Paper winding still occupies a considerable position in winding and is mainly used in oil-immersed transformers. The oil-paper insulation formed at this time has excellent dielectric properties, low price and long service life. In recent years, film winding has developed rapidly, mainly polyester film and polyimide film winding. Recently, there are mica tape coated polyester imine film coated copper flat wire for wind power generation.
