Problems solved by technology

[0002] The high lubricity of enameled wire is an inevitable requirement for the miniaturization and lightening of electrical appliances. At present, there are methods to improve the lubricity of enameled wire surface at home and abroad. 1. Apply a layer of lubricating oil to the surface of enameled wire insulating varnish. Alcohol, cyclohexane, and paraffin are mainly used, which are easy to volatilize and consume during the enameled wire process, which will not only bring serious pollution to the atmosphere, but also cause harm to human health
The second is to improve the lubricity of the insulating paint film itself. The fundamental method is to coat a layer of insulating paint with self-lubricating function on the surface of the enameled wire to make a self-lubricating enameled wire. Capacitance can also be improved
