Introduction to Dry - type Transformers
Dry - type transformers are electrical devices that transfer electrical energy between circuits through electromagnetic induction, without the use of a liquid coolant. Unlike oil - filled transformers, dry - type transformers use air or a solid insulating material to dissipate heat. They are widely used in various applications, such as commercial buildings, industrial facilities, and renewable energy projects, due to their safety, reliability, and environmental friendliness. Dry - type transformers are less prone to fire hazards compared to oil - filled transformers, and they require less maintenance. They also have a longer service life and can operate in a wider range of environmental conditions.
