Air Core Electric Arc Furnace Reactors

Arc Furnace Reactors are serially connected reactors that are installed in the supply systems of arc furnace transformers to stabilize arc and limit the unstable arc furnace current and voltage drop which optimize their melting process. These buffer reactors are connected in series to the primary side of the furnace transformer. Typically these reactors are tapped coils and manufactured as per customer's tap requirements.
