Furance Transformer - Induction & Melting

Furnace Transformers are used to supply power where there are high current requirements to electric furnaces of the induction, resistance, open arc, and submerged-arc types.
The secondary of furnace Transformers are generally low voltage are with high harmonics withstanding capacity.
