when using low-frequency transformers, we will find that the materials used in low-frequency transformers are quite different, and there are many classifications, but the commonly used ones are plastic. There are many kinds of plastics, some of which have strong tolerance, others can prevent deformation, and more importantly, they are very environmentally friendly, and their pressure resistance is also stronger than any other. It also plays a good role in resistance. If we can choose a thinner silicon steel sheet and improve the core material, the loss will be improved.
