An Oil Cooled Transformer is a high-performance electrical transformer designed for efficient power distribution, superior heat dissipation, and long operational life. Filled with specially formulated insulating oil, the transformer uses natural or forced oil circulation to remove heat from the windings and core, ensuring reliable operation even under heavy load or continuous duty conditions.

Built with high-grade copper or aluminum windings, robust core materials, and hermetically sealed tank construction, an oil-cooled transformer offers excellent cooling efficiency, electrical insulation, high durability, and extended service life. It is widely used in industrial plants, commercial establishments, utilities, and power distribution systems.

An Oil Cooled Variable Transformer is a heavy-duty variable autotransformer designed for applications that require continuous, stable, and adjustable AC voltage under high load conditions. The transformer is immersed in high-grade insulating oil, which provides superior cooling, enhanced insulation, and extended service life. This oil-cooling system ensures the transformer remains cool even during prolonged or high-current operation, making it ideal for demanding industrial environments.

Built with copper windings, a rugged core, and a durable carbon brush mechanism, the Oil Cooled Variable Transformer delivers smooth, stepless voltage regulation from 0 to 110% of input voltage without waveform distortion. It is widely used in industries, R&D labs, testing facilities, and heavy-duty load setups.
