Yes, many transformers are typically filled with oil, particularly those used in high-voltage applications. The oil serves two primary purposes: it acts as an electrical insulator, preventing electrical discharges within the transformer, and it provides cooling by dissipating the heat generated during the operation of the transformer. This oil-filled design is common in power transformers, distribution transformers, and other large electrical equipment.
