The color of the enameled wire is barely not relevant to the performance and usage.It is mainly classified by insulating materials and specific application.Enameled wire is a major type of winding wire, composed by two parts, conductor and insulation. After annealing and softening the bare wire, and then after many times of painting and baking.
Color will not affect the actual use, only the diameter of the enameled wire or thickness of the film will affect the amount. General enameled wire (common wire) is mainly used for general motor, electrical appliances, instrumentation. Winding wires used in transformers and other work occasions such as: polyester enameled wire, modified polyester enameled wire. According to the conductor material, there are 2 types which is copper, aluminum and alloy wires. According to the material shape, there are 3 types which is round, flat and hollow wires. According to the insulation thickness, there will be 3 types which are thin film-1, thick film-2, heavy thick film-3 for round wires.There is no need to distinguish between all the colors. But usually through intuitive observation, the golden yellow represents high thermal class enameled wire, dark brown is the common enameled wire. Xinyu can produce both types of enameled wires according to details requirements.
Because it is difficult to disperse nanoparticle in a viscous varnish solution, the sol-gel method, which has a great advantage for dispersion, has attracted attention. In the sol-gel method, nanoparticles are easily dispersed in the insulation layer as soon as they are synthesized from the precursors premixed in the varnish during the wire annealing process accompanied by a coating process. However, serious problems were revealed; for example, the enameled wire production cost increased because the process was too slow and the breakdown strength of the enameled wire was reduced due to impurities remaining from the sol-gel process . In order to avoid such problems, nanoparticles need to be directly dispersed in the varnish and therefore should be properly surface-modified.
