A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). The main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers are the basic equipment for power transmission and distribution, widely used in industries, agriculture, transportation, urban communities, and other fields.

European box-type transformer substation
The high voltage chamber of a European box transformer is generally composed of high voltage load switches, high voltage fuses, lightning arresters, etc. It can perform power outage and transmission operations and has overload and short circuit protection. The low-voltage chamber is composed of low-voltage air switches, current transformers, ammeters, voltmeters, etc. Transformers are generally made of S9 or dry-type. The electrical equipment components in the European box transformer are all selected from standardized products, and the technical performance of the components meets the corresponding standard requirements.
