Part four - application chapter XII engineering applications

Progress in the application of insulation to rotating electrical machines has continued unabated throughout 1958. Particularly evident in the literature is the effort of engineers to use more of the new synthetics, which are available in such abundance, as well as improved and modified conventional and natural materials. Many of these new and modified materials have, by ingenious means, been combined and integrated into practical insulation systems designed to meet particular requirements of a manufacturer of rotating machines or of a user industry. From the standpoint of application, a material, per se, has little value as a dielectric until it can be proved to perform suitably in combination with other components which are required to provide a physically (mechanically and thermally) sound insulation system.
