Understanding Dry Type and Oil Immersed Transformers

Dry type transformers are an essential component in electrical systems, particularly in medium voltage applications. These transformers use air as a cooling medium and are known for their safety, reliability, and low maintenance requirements. They are often used in indoor installations where space is limited and environmental conditions need to be controlled.

On the other hand, oil immersed transformers utilize oil as both a coolant and insulator. This type of transformer is typically more efficient at dissipating heat and is commonly used in outdoor settings due to its robust design. The choice between dry type and oil immersed transformers often depends on the specific application and environmental factors.
