Oil-Immersed Distribution Transformer is an essential component in modern electrical distribution networks, designed to convert high-voltage electricity from transmission lines into lower voltages suitable for commercial, industrial, and residential use. This type of transformer uses high-quality insulating oil to provide both effective cooling and electrical insulation, ensuring stable and safe operation even under heavy load or fluctuating environmental conditions. Because of its outstanding efficiency, long service life, and superior thermal management, it remains one of the most widely used transformer types worldwide. The structure of an oil-immersed distribution transformer includes a magnetic core , windings , insulating oil , and a sealed steel tank . The core, typically made of cold-rolled silicon steel sheets, minimizes magnetic losses, while the copper or aluminum windings are engineered for optimal electrical conductivity and mechanical strength. The entire assembly is su...

Power transformers  are essential components in electrical power systems, designed to transfer electrical energy between different voltage levels with maximum efficiency. They are primarily used in transmission networks to step up the voltage for long-distance power transfer or step it down for distribution to substations. Unlike distribution transformers, power transformers operate at higher voltages and handle large power capacities, often ranging from several megavolt-amperes (MVA) to hundreds of MVA. They are typically installed in generation plants, transmission substations, and industrial facilities where heavy electrical loads are common. The core of a power transformer is built from high-grade silicon steel laminations to reduce eddy current losses, while the windings are made of copper or aluminum to ensure high conductivity. Most power transformers are oil-immersed, using insulating oil for both cooling and electrical insulation. However, recent developments in dry type...
