120MVA Arc Furnace Electrical Oil Immersed Power TransmissionTransformer
General
Electric furnace Transformer (EAF) is using electricity as fuel source, and utilizes the arc high temperature produced by electrode and furnace charge to heat and melts the furnace charge.
It has more stringent requirements in electric, magnetic, thermal, mechanical and other aspects compared with other transformers, and has to comply with the operation process of various furnace transformers and load characteristics, so that it can meet users, and facilitate energy-saving emission reduction and other conditions.
