Product Description

Electric Arc Furnace Transformer that presented by us is designed to be utilized for providing electric energy to the arc furnaces. This kind of transformer helps in converting the electric energy into heat energy. It comes with a non-resettable device to detect internal faults of transformer, utilizes pressure relief, and offers an external indication which is visible from the ground. Engineered and developed by proficient engineers with developed electrical technology, Electric Arc Furnace Transformer can be availed in varied models, powers and specifications at negotiable prices.
