深圳There are many kinds of enamelled wires but they have common properties

There are many kinds of enameled wire, and although their quality characteristics are different due to various factors, there are also some similarities. Let's look at the manufacturers of enamelled wire.

The early enamelled wire is oil-based enamelled wire made of tung oil. Due to its poor wear resistance, it can not be directly used to manufacture motor coils and windings, so cotton wrapping layer should be added when used. Later appeared the polyvinyl formaldehyde enamelled wire, because of its good mechanical properties, can be directly used in the motor winding, so it is called high strength enamelled wire with the development of weak current technology, self-adhesive enamelled wire appears again, without dipping, baking can obtain good integrity coil. However, its mechanical strength is poor, and it can only be used for micro motors and small motors. Until later, with the improvement of people's aesthetic, colorful enamelled wire appeared.

Enamelled wire is the main type of winding wire, usually consisting of a conductor and an insulating layer. After annealing and softening, the bare wire is painted and baked several times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It will be affected by raw material quality, process parameters, production equipment, environment and other factors, so the quality characteristics of various enameled wire are different, but they all have four major properties: mechanical properties, chemical properties, electrical properties and thermal properties.
