Fully Sealed Oil-Immersed Power Transformers
A fully sealed oil-immersed power transformer is a type of electrical transformer designed for high reliability, minimal maintenance, and long service life in a variety of power distribution and industrial applications. Unlike conventional oil-immersed transformers that feature a conservator tank (breathing type) to accommodate oil expansion, the fully sealed design eliminates contact between the insulating oil and the atmosphere, ensuring superior protection against moisture and oxidation.
