Xinyu Introduced The Details Of The Enamel Aluminum Wire

Posted By enameledwire xinyu     December 12, 2018    


Early use of cotton yarn and silk, known as yarn wrapped wire and wire wrapped wire, was used in motors and electrical appliances. Due to the large thickness of the insulation and low heat resistance, most have been replaced by enameled wires. It is currently only used as a high frequency winding wire. In the large and medium-sized winding wires, when the heat resistance level is high and the mechanical strength is large, the glass fiber covered wire is also used, and the appropriate adhesive paint is used in the manufacture.

In the enameled wire, the paper covered wire still occupies a considerable position, mainly used in oil-immersed transformers. The oil-paper insulation formed at this time has excellent dielectric properties, is inexpensive, and has a long life. The paper covered wire is a wire which is annealed or drawn after being pressed or drawn by an oxygen-free copper rod or an electric round aluminum rod, and then wrapped on a copper (aluminum) conductor to wrap two or more layers of insulating paper (including Winding wire for telephone paper, cable paper, high-voltage cable paper, inter-turn insulating paper, etc., suitable for oil-immersed transformer coils and other similar electrical windings. The bare copper (aluminum) wire produced by the extrusion process is the most ideal material for producing cable paper covered wires.

In recent years, the film enameled wire has been developed more rapidly, mainly including polyester film and polyimide film wrapping wire. Recently, there are also mica-coated polyesterimide film wrapped copper flat wires for wind power generation. When the heat resistance level is required to exceed the limit of the organic material, it is usually coated with an inorganic insulating varnish. The existing inorganic enameled wire can be further classified into glass film wires, oxide film wires, and ceramic wires.
