Oil Immersed Hermetic Sealed Transformer

The Fully Sealed Oil Immersed Transformer, also referred to as Sealed Transformer Oil Immersed, Oil Filled Sealed Transformer and Enclosed Oil Immersed Transformer, is a durable electromagnetic power conversion device designed for outdoor and heavy-duty power distribution projects. It adopts an all-welded fully sealed tank structure that isolates internal insulating oil from external air, moisture and dust. Unlike conventional conservator-type transformers, this oil filled sealed transformer avoids oil oxidation, moisture absorption and condensation, slowing down insulation aging and oil deterioration. Equipped with electrolytic copper windings and grain-oriented silicon steel sheets, it realizes optimized electromagnetic circuitry to reduce no-load loss, load loss and operating noise while ensuring stable voltage regulation. The high-purity insulating mineral oil provides excellent thermal conductivity and dielectric strength for efficient heat dissipation and reliable insulation. Wit…
