Classification of enameled wire in transformer


Enameled wire is a main type of winding wire. Winding wire is a conductive metal wire with an insulating layer. It is used to wind the coils or windings of electrical products such as transformers, motors, and inductors. Enameled wire consists of two parts: conductor and insulating layer.
Enameled wire, also known as magnet wire, is a copper or aluminum wire coated with a very thin layer of insulation. This type of wire is primarily used in applications requiring tight coils of wire, such as in transformers, motors, and inductors.


enameled wire in transformer


A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are the primary coil, the secondary coil, and the magnetic core. In electrical equipment and wireless circuits, it is often used to increase or decrease voltage, match impedance, and provide safety isolation.
In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a fixed coil, an electric potential can be induced in the coil. In both cases, the value of the magnetic flux remains unchanged. However, the amount of magnetic flux interlinked with the coil changes, which is the principle of mutual induction.
A transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.
In transformers, enameled wire is a commonly used type of wire, usually used to wind the coil of the transformer. Enameled wire is an insulated wire with an insulating enameled coating on the surface of the conductor. Enameled wire is provides electrical insulation and protect the conductor.

Enameled wire is a critical component in the construction and operation of transformers. Its properties, such as high electrical conductivity, superior insulation, and heat resistance, make it an ideal choice for various types of transformers. The use of enameled wire enhances the efficiency, durability, and compactness of transformers, making it indispensable in modern electrical systems.
By understanding the importance of enameled wire, manufacturers and engineers can optimize transformer designs for better performance and reliability in electrical power distribution and management.


According to the material and purpose of the conductor, enameled wire can be divided into the following categories:
1. Enameled copper wire: The conductor is made of copper, which is the most common type of enameled wire. It is used for general transformer winding and electrical equipment such as motors.
2. Enameled aluminum wire: The conductor is made of aluminum. Commonly used in medium and low voltage transformers and electrical equipment.
3. Copper-aluminum alloy enameled wire: The conductor is made of copper-aluminum alloy. It has good conductivity and corrosion resistance and is suitable for special occasions.
4. High-temperature enameled wire: The conductor and insulating enameled layer have high high temperature resistance. It is suitable for transformers and electrical equipment in high temperature environments.
5. Ultra-fine enameled wire: The conductor diameter is very fine. Commonly used in micro transformers and electronic equipment.
6. Oil-immersed transformer: Generally use polyimide enameled wire with high temperature resistance and good insulation performance.


In general, enameled wires are classified according to the different conductor materials, uses and performance. In transformers, it is very important to choose the right type of enameled wire to ensure the stable operation and electrical performance of the transformer.
