What are Cooper transformers oil-filled types?

Cooper transformers oil-filled types primarily include mineral oil-filled transformers, synthetic oil-filled transformers, and natural esters or bio-oil-filled transformers. Each type has distinct properties and applications. Mineral oil-filled transformers are the most common due to their good insulating and cooling properties. Synthetic oils offer enhanced performance in extreme conditions, reducing environmental risks. Natural esters provide an eco-friendly alternative with a higher flash point and greater biodegradability, making them suitable for installations in environmentally sensitive areas. Understanding these options helps in selecting the right Cooper transformers oil-filled type for specific operational needs.
