Transformer specifically designed to provide power for various electric furnaces. Resistance furnace transformers are used in resistance furnaces and salt bath furnaces for heating mechanical parts, heat treatment, powder metallurgy sintering, and non-ferrous metal smelting. Because the resistance of the heating element is too low, or because the resistance of the heating element becomes too large during the heating process, a resistance transformer needs to be equipped between the furnace and the power grid to reduce and regulate the input voltage of the electric furnace. Small capacity, low voltage resistance furnace transformers and salt bath furnace transformers are mostly dry-type transformers, housed in enclosures, and naturally cooled; medium capacity (hundreds to thousands of kVA) resistance furnace transformers are mostly oil-immersed self-cooled transformers; large capacity transformers are forced oil circulation water-cooled transformers.
