What are the key parts of an oil-immersed transformer?

The key parts of an oil-immersed transformer include the core, which is typically made of laminated steel to reduce energy losses, windings that are insulated and facilitate the transformation of voltage, and the insulation oil that serves both as a dielectric and cooling medium. Additionally, the conservator tank is crucial for maintaining oil levels and accommodating thermal expansion, while the breather helps keep the oil moisture-free. Lastly, protective fittings such as Buchholz relays and temperature sensors ensure safe operation. Understanding these components is essential for anyone involved in maintenance or manufacturing, especially an oil immersed transformer manufacturer, to ensure optimal functionality and longevity of the transformer.
