Keywords: , , , ,

Polymer nanocomposites are defined as polymers in which small amounts of nanometer size filers are homogeneously dispersed. In power industry, electrical insulating polymers usually incorporate inorganic fillers to achieve specific electrical, mechanical, thermal properties and reduce cost. In recent years, the polymer based nanocomposites with good electrical and thermal properties have drawn more and more attention of the research and industry people in the field of dielectrics and electrical insulations, especially in manufacturing large high voltage rotating machines such as Rotors and Generators. The progress, advantages, limitations, and current problems of using polymer nanocomposites as dielectric materials will be discussed in this review. It is found that several research groups worldwide have now been able to document some significant improvements that potentially can be made in the electrical, thermal and other properties of polymer nanocomposites through the incorporation of nano-particulates. However, we still have a long way to go in terms of understanding the mechanisms of the nano enhancement effect of nano materials on electrical insulation and its successful commercial applications in the power generation industry.
