The production process of small transformers?

Everyone knows that small transformers are sometimes used in life or work. For example, they can be seen in various electronic devices. So how is it composed? I believe you are as curious as me, so let’s learn about it together with you. The composition of the small transformer.
1. Winding: The windings of small transformers generally use enameled wires, usually in the form of double windings. The primary side of the transformer has only magnetic connections, no electrical connections. At the same time, it can be divided into core-shell structure.

2. Iron core: Its core has E shape, C shape, R shape, ring shape, etc. Type E is used for low power transformers, and Type C is used for electronic equipment, instrumentation and household appliances. It has the advantages of light weight, small volume, small magnetic leakage, low loss, and low temperature rise.
3. Fixed bracket: The fixed bracket is used to fix and support the transformer. Its material can be iron plate or aluminum plate. The shape and fixation of the bracket are determined according to the shape and power of the iron core.
4. Insulating material: In order to make the transformer have sufficient insulating strength, thin insulating materials, such as capacitor paper, yellow wax wire, etc., can be placed in the winding layer. In some occasions requiring high insulation, polyester film, Teflon film, etc. can also be used .
