Oil-filled transformer bushings are crucial components in electrical transformers, serving as insulating conduits that allow electrical conductors to pass through transformer tanks. Their primary role is to provide electrical insulation between the high-voltage internal components and the grounded metal casing, preventing electrical leaks and ensuring operational safety. The oil within these bushings not only enhances insulation but also assists in heat dissipation, providing thermal stability for the transformer system. Additionally, the oil helps to minimize the risk of moisture ingress, which can compromise the dielectric properties and overall performance. Proper maintenance of oil-filled transformer bushings, including cleaning and ensuring the integrity of the insulating oil, is essential for the longevity and reliability of transformers.
