Cast Resin Dry Type Transformer (CRT)

A cast resin dry type transformer (CRT) is a type of transformer that uses epoxy resin to encapsulate its primary and secondary windings. This protects the windings from moisture, dust, corrosion, and other environmental factors that can affect their insulation and performance. A CRT is suitable for high humidity areas, indoor installations, and fire-risk areas because it is non-hygroscopic, non inflammable, and maintenance-free. It can also withstand overloads, partial discharges, and low losses, resulting in high efficiency and long service life.
