OEM Supply Varnish Insulating For Insulating Copper Magnet Wire - 0.071mm Enameled Copper Wire for Electric Motor Winding – Ruiyuan Detail:

Enameled Copper Wire for Electric Motor produced by our company has good performance to resist high heat, abrasion, and corona. After years of practice from R&D to mass production, we develop our own patent technical solutions which is metal conductor(copper wire) is enamelled with a basic heat-resistant layer of polyesterimide covered with another layer of polyamide-imide resin. This structure of compound coating over copper wire contributes to excellent properties of our enameled copper wire, including higher thermal class, good corona resistance and enamel protection. Thus for applications that require high temperature resistance, such as high temperature motors, load motors, air conditioner compressors, refrigerator compressors, water dispensers. and other products, our enameled copper wire is the best solution.

Modified polyester or polyesterimide with thermal class 200 as base coat not only increases heat resistance but also maintains scratch resistant property that class 180 enameled copper wire have. Polyamide-imide resin with a temperature rating of 220 featuring solvent resistance, excellent breakdown voltage performance and smooth surface is used as extra coat so that thermal class, corona resistance, enamel protection and other properties of the enameled copper wire are improved. All these properties makes our enameled copper wire with thermal class 200 suitable for use to high temperature motors, load motors, air conditioner compressors, refrigerator compressors, water dispensers and other products.

Besides, coats of our class 200 enameled copper wire: the weight of modified polyester or polyesterimide resin accounts for 70% to 80%, while polyamideimide resin coat accounts for 20% to 30%. Since unit cost of polyamide-imide resin is generally 160% of that of polyesterimide, a small proportion of polyamideimide cuts the cost and also ensures compound coating. As it is difficult to achieve smooth surface, we need to make technological adjustment to manufacture, such as increase of the cooling air volume to keep it well coated and two rows of paint roller for compound coating.
