Insulation for 500°C motors and generators

Space vehicles of tomorrow must depend on electrical insulation which can function at temperatures up to 500°C. Weight limitations will prevent cooling systems for the electrical equipment. Such a radically new insulation system has already been explored and is briefly described below: The requirements of an insulation system for electrical equipment subjected to 500°C are not only for individual forms of electrical insulation which can be processed but also for a completely compatible system of both insulation and electrical and mechanical components. The individual requirements of the insulation are also outlined.
