technical field

The invention relates to the technical field of transformers, in particular to a dry-type transformer core forming equipment and a forming process.

Background technique

A transformer refers to a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, the secondary coil and the iron core; the iron core is an indispensable core component that constitutes the magnetic circuit of the power transformer, and it is the main magnetic core of the transformer.
