Advanced NAno-Structured TapeS for electrotechnical high power Insulating Applications

The European ANASTASIA project is introduced, recalling the objective, rationale, and approaches driving its deployment. The application-driven context involves complex insulation systems consisting of mica tapes impregnated with epoxy resin. In view of the long-standing service experience of using such systems, the ANASTASIA consortium set out to enhance the present tape technology using nanodielectrics. This report focuses on the study of relevant and privileged fillers of nanometric dimensions and their effect in changing the macroscopic properties of their nanocomposites in the context of HV rotating machinery insulation. In view of the objective to explore the extent to nanostructuring can lead to material systems capable of withstanding increased design fields, with improved thermal conductivity and which attain class H, only breakdown behaviour, thermal conductivity and thermal degradation are considered here.
