Power Transformer
In StockA Power Transformer is a high-capacity electrical device designed to efficiently transfer electrical energy between circuits while stepping up or stepping down voltage levels in power generation, transmission, and distribution systems. It operates on the principle of electromagnetic induction, ensuring reliable voltage regulation and minimal energy loss over long distances.
Power transformers are essential components in power plants, substations, industries, and utility networks, where they handle large amounts of electrical power. Constructed with high-grade copper or aluminum windings, laminated silicon steel cores, and superior insulation, a Power Transformer delivers high efficiency, low noise, and long operational life.
