Top 10 dry type transformer Suppliers in the world 2025 - Blog

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, hospitals, data centers, and industrial facilities due to their safety, reliability, and environmental - friendliness. Dry type transformers are less prone to fire hazards compared to oil - filled transformers, which makes them a preferred choice in areas where fire safety is a major concern. They also require less maintenance and have a longer service life, making them a cost - effective solution in the long run.
