This document discusses solutions for improving insulation performance in generators and motors. It provides encapsulation and impregnation solutions for low and high voltage applications that offer benefits like high mechanical strength, excellent dielectric properties, and high temperature resistance. It also discusses solutions for small motors, generators, and rotating machines that improve endurance, enable fast processibility, and provide high thermal conductivity and resistance to cracking and heat. The document promotes a partnership between Huntsman and Isovolta for a certified, solvent-free Class H insulation system tested and approved as a combination of impregnation resin and mica tape.

- 12. Advanced Materials 12 VPI systems for all insulation processes VPI vs prepreg Depending on the size of the machine and the size of the impregnating plant the choice will be between either single bar or global impregnation. The majority of manufacturers have switched to Vacuum Pressure Impregnation, because VPI offers some advantages in mechanical and electrical properties compared to the prepreg method. For example with global impregnation, in addition to the lower risk of voids, much better fixation of the coils and especially the end windings is possible. < Table of content Small motors > Generators / rotating machines >Raising performance > Partnership >
