The use of enameled wire is extensive, not to be underestimated!
- Jan 11, 2018 -


Enameled wire is a main type of winding wire, consisting of two parts: conductor and insulating layer. After annealing and softening, the bare wire has been painted and baked several times.

But to produce both conform to the requirements of the standard, and it is not easy to meet customer requirements of product, it is raw material quality, process parameters, production equipment, the environment factors, therefore, all sorts of enameled wire quality characteristics of each are not identical, but all have mechanical properties, chemical properties, electrical properties, thermal properties of four performance.

Generally speaking, enameled wire can be divided into:

1. General purpose enameled wire (ordinary line) : mainly used for general motors, electrical appliances, instruments.

Winding wire of transformer and other work place.

2, heat resistant enameled wire, mainly used for motor temperature above 180 ℃, and the environment, electrical appliances, instruments, transformer and so on the workplace of the winding line.

3. Enameled wire for special purpose: it refers to the enameled wire with certain quality characteristics, which is used for winding wires of specific occasions.

When the enameled wire is wound into a coil, it is usually impregnated. The solvent in the impregnating varnish has a different degree of swelling effect on the paint film, especially at higher temperatures.

After dipping in use process, the winding due to the effect of thermal film may produce thermal cracking, so the stand or fall of impregnating varnish and enameled wire paint film intermiscibility for the service life of motors, electrical appliances, instruments are affected.

In use process, winding may contact with around a variety of media, such as contact with the refrigerant in the refrigeration unit, contact with all kinds of chemicals in the chemical plant, the medium of paint film have different degrees of corrosion effect, salt fog of Marine electrical products on enameled wire can also generate chemical corrosion, etc., so the enameled wire paint film has good chemical stability.
