Abstract

Various embodiments include a sprayable formulation for production of a multilayer insulation for an electrical machine, especially a rotating electrical machine in the high-voltage or mid-voltage sector, for example a generator, transformer, which is subjected to higher rated voltages at operating voltages, i.e., for example, over and above 1 kV or more. The invention also relates to an electrical machine comprising such an insulation; the invention finally relates to a method of producing the multilayer insulation. This comprises spraying of various formulations with or without intermediate, especially metallic, interfaces and is automatable.
