The electromagnetic line is also called winding wire, and the insulation materials and manufacturing methods used in the insulation layer are divided into enameled wire, wrapping wire, enameled wrapping wire and inorganic insulated wire.

The earliest enameled wire is an oily enameled wire made of tung oil, which has poor abrasion resistance and can not be used directly to make motor coils and windings.

Later, polyvinyl formal enameled wire was introduced, and its mechanical properties were greatly improved. It could be used directly in the motor winding, and it was called high strength enameled wire.

With the development of the weak current technology, there is a self-adhesive enameled wire, which can not be impregnated and baked to obtain the whole better coil.

But its mechanical strength is poor, only can have micro - motor, small motor to use.

In addition, in order to avoid the trouble of removing the paint film before welding, it developed the direct welding enameled wire, and its coating can fall off itself in the high temperature tin groove and make the copper wire easy to weld.

The application of enameled wire is becoming more and more extensive and demanding.

Enameled wire used according to its insulation paint can be divided into polyester, polyester imide enamelled wire, polyimide, polyamide imide enameled wire enameled wire enameled wire, polyamide imide, corona resistant enameled wire, and paint, acetal paint, polyurethane enamelled wire, etc.

Sometimes it is classified according to its special purpose, such as self-adhesive enameled wire and refrigerant enameled wire.
