What are the characteristics of oil-type transformers?

Oil-type transformers are characterized by their use of insulating oil for cooling and insulation. This oil helps dissipate heat generated during operation, enhancing efficiency. They typically feature a sealed tank to prevent moisture ingress and maintain insulation integrity. Additionally, oil-type transformers have a higher thermal capacity, allowing for greater load handling. Their design also facilitates easier maintenance and monitoring of oil quality, ensuring reliable performance in various applications.
