Power transformers use special mineral oil not just for cooling but as an electrical insulator. The oil prevents electricity from arcing between high-voltage components while transferring heat away from the transformer's core. A single large power transformer can contain over 100,000 liters of this specialized oil. If the oil degrades or becomes contaminated with moisture, it can lead to electrical failures and even fires.
