With the increasing dependence of human beings on electric energy, transformers have become an indispensable part of various electrical appliances. High-frequency transformers are widely used due to their advantages of small size, high efficiency, and low cost. What kind of materials does it use?

1. Enameled wire

Copper wire is one of the basic materials for making transformers, which can complete the most basic function of transformers --- voltage conversion.

2. Wire frame and base

The wire frame and the base are the skeletons that support the coils, and together with the pins, they form a complete bobbin, so that the incoming and outgoing lines of the transformer can be easily wrapped and welded on the pins.

3. iron core

The iron core for high-frequency transformers should be more appropriately called the magnetic core, which is made of ferrite magnetic powder sintered at high temperature. The role of the iron core is to increase the strength of the magnetic field to form a loop.

4. Silicon steel sheet

There are different materials according to the amount of steel contained in it. Generally speaking, silicon steel sheets with more steel content are heavier than those with less content, and can be divided into two types: calcined (brown) and non-calcined (gray white). The thicker the silicon steel sheet, the greater its eddy current loss and the higher the temperature rise.

5. Tape

Tapes are often used in transformers. The main functions of tapes in transformers are three-point: insulation, filling and fixing.
