, the iron core is usually made of 0.35mm

The winding is also one of the basic components of a transformer. It is the circuit part of the transformer, generally wrapped with copper or aluminum wires wrapped in insulating paper. The winding connected to the high-voltage network is high-voltage winding, and the winding connected to the low-voltage network is low-voltage winding. The winding acts as the carrier of current, generating magnetic flux and induced electromotive force.
