The influence of thermal properties of aluminum oxide on electrical insulating materials

This article describes the influence of thermal material properties on the properties of electrical insulation materials and heat transfer in electrical devices. When increasing performance and decreasing dimensions of electrical equipment the losses grow. It is necessary to search new materials which can fulfill greater demands. Thermal properties of materials are one group of important aspects. By adding filler with good thermal conductivity to a composite can be increased its thermal conductivity. Heat transfer takes place in three ways by conduction, convection and radiation.
