how much copper is in a 3 phase transformer?

The amount of copper in a 3-phase transformer varies based on its design, size, and power rating. Typically, the copper content can range from a few hundred kilograms for smaller transformers to several tons for larger industrial units. The copper is primarily used in the windings, and its quantity is determined by the transformer’s voltage, current ratings, and efficiency requirements. For precise calculations, refer to the transformer’s specifications and design parameters.
