Dry Type Transformers

The Most Advanced Power Transformers on the Market

Dry-Type-TransformerWhat Are the Basics of Dry Type Transformers?

Transformers change voltages from one level to another.  Most commonly, that change involves very high-power line transmission voltages (500 kV) being reduced to the much lower levels used in heavy industry (as much as 30 kV).  Dry type, or air-cooled, transformers accomplish this function so safely and efficiently that they are commonly used for indoor applications where other transformer types are considered too risky.
