What is the difference between foil winding and wire winding in transformers?
Foil winding refers to the winding made by winding aluminum foil or copper foil, and one turn is one layer. Foil winding is suitable for low voltage, high current transformer.Wire winding means winding with one or more wires in circles, mainly used for transformers with rated current below 200Ampere.Foil winding is convenient to make, high efficiency, stronger short-circuit resistance, and less loss. However, the height of the coil is limited by the height of the foil, and a special foil winding machine is required.Wire winding is relatively complex to make, but the cost of the conductor material is relatively low, the height of the coil is not limited, it has good heat dissipation performance.
