1. The toroidal transformer is mainly composed of three parts: iron core, copper-aluminum wire, and insulating material. 2. Toroidal transformers are customized products and cannot be fully coordinated with the entire installation without providing detailed parameters. 3. The input and output of the toroidal transformer can be divided into two or more windings. Can be designed according to user requirements. 4. There are many types of toroidal transformers. According to industry use, it can be divided into: power amplifier toroidal transformer, medical toroidal transformer, power output toroidal transformer, solar wind energy toroidal transformer.
