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.

Although there are many kinds of enameled wire, it does have some common performance characteristics.

First of all, good insulation performance is the basic requirement of all types of enamelled wire. This can effectively prevent current leakage and short circuit to ensure the safe and stable operation of the circuit. Whether it is enamelled wire used in small electronic devices, or enamelled wire in large industrial equipment, insulation performance is crucial.

Second, enamelled wire usually has a certain flexibility. This allows them to withstand operations such as bending and twisting during installation and use without breaking or damaging the insulation. For example, in some electrical appliances that need to move or bend frequently, the flexibility of enameled wire is particularly important.

In addition, all kinds of enamelled wires need to have better corrosion resistance. They should be able to resist the erosion of moisture, chemicals, etc. under different environmental conditions, so as to maintain good electrical and mechanical properties.

In addition, enamelled wire generally has a relatively stable resistance value. This helps to ensure the stable transmission of current and voltage, reducing energy loss and heating.

Finally, good adhesion is also one of the common properties. The paint layer can be firmly attached to the surface of the wire and is not easy to peel off, so as to effectively play the role of insulation and protection for a long time.

In short, despite the variety of enamelled wires, their common performance characteristics ensure their wide application in different fields and equipment.

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.
