Dry-type transformers, also known as cast resin transformers, are power transformers with windings encased in epoxy resin. This makes the installation process easier because they are dry and do not require cooling oil. Plus, they do not need to be contained in a fire-proof vault. The layer of epoxy helps protect it against dust and corrosion. Dry-type transformers are used in a wide variety of applications and can be installed indoors or outdoors.

Transformers are used to increase or decrease voltages and currents in an electrical circuit. There are a variety of transformers out there, including liquid-type transformers, but there are plenty of good reasons why we recommend dry-type transformers. They are more economical, they pack important safety features, and they are more efficient.
