Epoxy resin is widely used in high voltage apparatus, electrical machines etc due to its excellent mechanical, electrical and chemical properties. Great progress has been made in application on electrical insulation, casting and potting. The epoxy resin containing nano-size and micro-size Al2O3 of various contents are prepared. The purpose of efforts we engaged in is to study the efforts of nano Al2O3,...
The results of comparative tests of the main electrophysical properties of a new type of high-efficiency heat-conducting insulation for turbo generators with air and hydrogen cooling as compared to the traditional insulation are presented. It is shown that the addition of modified varnish with a high thermal conductivity coefficient to the insulation material does not yield any deterioration of its...
