Abstract

An insulating system having improved partial discharge resistance includes an insulating tape around a conductor. The tape is a mica tape joined to a carrier. The tape is impregnated with a synthetic resin, and is interspersed with a nanoparticulate filler, present bimodally, in the form of two fractions of the filler differing in particle size and fraction size. An adhesion promoter may be in the resin.
