A furnace transformer is an essential component in industrial applications, especially in metallurgy and metal processing. It plays a crucial role in supplying the high voltage and current required for electric arc furnaces, induction furnaces, and other heavy-duty heating equipment used in smelting and refining metals. Furnace transformers are designed with multi-tap windings to adjust the voltage for different furnace operations, ensuring energy efficiency and stable power supply. They find applications in steel production, non-ferrous metal processing, foundries, and heat treatment processes. Regular maintenance is crucial to their reliable operation, and safety features are integrated to protect against electrical faults and overloading, making them a vital part of industrial manufacturing
