Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, and voltage stabilization (magnetic saturation transformer). A transformer is a device that uses electromagnetic mutual induction to convert voltage, current and impedance.

[0003] In the transformer, the switch, voltage-equalizing tube and copper busbar need to be led out through copper stranded wire. The transformer lead bracket is an important transformer component.
