Technical requirements for Dry Type Transfomers (DDT) are every day more demanding due to different conditions of operation and thermo-electric stresses. Storage and operation at very low temperatures and higher thermal class (from 180 °C up to 200 °C) coupled with easy and robust processing represent the main challenges. This trend is confirmed also by evolution of regulations by IEC, GOST and other regulatory bodies. The status of the art in terms of regulations and properties of the currently used materials will be reviewed and new developments to match the new requirements highlighted.
