Oil is commonly used as an insulator in electrical transformers to prevent electrical discharges and provide cooling. The oil acts as a dielectric material, which means it can withstand high voltages without conducting electricity. The oil also helps dissipate heat generated during the transformer's operation, ensuring efficient performance and preventing overheating. Additionally, the oil helps to insulate the transformer's components from moisture and contaminants, extending the lifespan of the equipment.
