Three Phase Auxiliary Transformer
In StockA Three Phase Auxiliary Transformer is a robust and efficient electrical device designed to provide power to auxiliary systems and equipment within industrial plants, substations, and power generation units. It steps down the main high-voltage supply to a lower voltage level suitable for operating essential auxiliary load such as lighting, control panels, pumps, fans, and instrumentation systems.
By supplying reliable secondary power, it ensures smooth, uninterrupted functioning of critical support operations in large electrical networks. Built with high-quality copper windings, low-loss laminated cores, and superior insulation, the Three Phase Auxiliary Transformer delivers excellent performance, low power losses, and long operational life.
