Core of a transformer

The core of a transformer serves as the magnetic circuit and framework of the transformer. Its core functions can be summarized as "magnetic conduction" and "efficiency enhancement". Specifically, its main functions are as follows:

1. The core is made of silicon steel sheets with high magnetic permeability, providing an efficient magnetic circuit for the transformer.

2. It improves the efficiency of the transformer.

3. It reduces the no-load current and lowers the reactive power loss of the transformer.

4. It provides support and fixation for the windings.
