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.
