Auxiliary Transformer
In StockAn Auxiliary Transformer is a compact and efficient electrical device designed to supply power to auxiliary or supporting systems within industrial plants, substations, and power stations. It steps down the high main supply voltage to a lower voltage suitable for operating control circuits, lighting systems, fans, pumps, and other auxiliary equipment.
By ensuring a stable and continuous power supply, it supports the smooth functioning of essential secondary systems that keep main electrical operations running efficiently. Built with high-quality copper windings, laminated magnetic cores, and durable insulation materials, the Auxiliary Transformer ensures high efficiency, low power loss, and long operational life.
