Power Auxiliary Transformer
In StockA Power Auxiliary Transformer is a high-performance electrical device designed to provide dependable power to auxiliary or supporting systems within power plants, substations, and industrial facilities. It steps down high transmission voltages to lower levels required for operating essential auxiliary loads such as control panels, lighting circuits, pumps, fans, compressors, and monitoring systems.
By supplying stable secondary power, it ensures the smooth and uninterrupted functioning of critical support equipment that keeps main power operations running efficiently. Manufactured with premium copper windings, low-loss laminated magnetic cores, and durable insulation, the Power Auxiliary Transformer guarantees excellent efficiency, minimal power loss, and long operational life.
