Understanding Dry Type and Liquid Filled Transformers
Dry type transformers are designed to operate without any liquid insulation. They often use air or resin for cooling and insulation, making them an environmentally friendly option. These transformers are typically used in indoor applications where safety is paramount. The absence of oil means there is a reduced risk of fire hazards, making dry type transformers an ideal choice for commercial buildings and industrial facilities.
On the other hand, liquid filled transformers rely on oil as both an insulator and a coolant. This design allows them to handle higher power levels and operate efficiently in outdoor settings. Liquid filled transformers are widely used in substations and large industrial plants. Their durability and ability to manage heat effectively make them a superior option for medium voltage applications.
