The Dry Type Transformer uses air for the cooling of the device and is safer option as compared to oil type which is widely used in transportation hubs and company buildings. This system is highly effective and are resistant to chemical contaminants as they do not contain any liquid medium for cooling. The windings and core of the dry type transformer are kept within a sealed tank that is pressurized with air. It is an efficient system with a high mechanical strength and are free from temperature fluctuations. There is very less requirement of maintenance and the device is less prone to the fire hazards.
