Oil-Immersed Transformer with Mineral Insulating Oil High Voltage Electrical Power Transformer

An oil-immersed transformer is a transformer that operates with its core and windings completely submerged in a sealed oil tank filled with special insulating mineral oil. It follows Faraday's law of electromagnetic induction to achieve voltage transformation and energy transmission. The insulating oil also performs three core functions: insulation, heat dissipation, and arc suppression (with high breakdown voltage, better thermal conductivity than air, and the ability to quickly suppress internal arcs).
