Electric insulation for energy-saving equipment

Equipment is labelled as energy-saving if it requires less energy during its manufacture and operation. A reduction in energy consumption in the manufacture of large electrical machines and equipment can be obtained by reducing their dimensions with their power preserved; To achieve this, new insulating materials characterized by high thermal conductivity must be used to increase the capacity to carry away the heat generated in the windings. This paper presents a technique of obtaining insulating composites with increased thermal conductivity, results of tests on composites and the use of these materials in high-power electric machines and for the production of HV insulators with increased resistance to surface discharges.
