Furnace transformer is specially designed to withstand high currents, mechanical, and thermal stresses. It is capable of handling extra high currents compared to conventional transformers, making it suitable for furnace applications. The large low voltage variation ensures that it can perform efficiently even under extreme conditions. The transformer also features OFWF cooling with 100% standby capacity, which makes it capable of withstanding repeated high mechanical and thermal stresses caused by electric arcs. In short, this transformer is built to provide reliable performance in demanding industrial environments.
