Every manufacturer in capacitor industry is dedicated to reduce the process time of capacitor vacuum impregnation

save energy and reduce consumption.In this paper the structure

connection method and specific adoption measures of a kind of capacitor vacuum drying and impregnating equipment with internal cooling system are introduced.The remarkable feature of such equipment is that it has such two independent systems as vacuum drying & heating and vacuum cooling

solving successfully the problem among vacuum and cooling

"mass transfer"and "heat transfer".The equipment

thanks to its perfect cooling function

shortens the cooling time significantly

assures and maintain normal heating temperature at vacuum stage and achieves such effect as time saving

energy saving and quality assurance.It is a new technology which can be promoted and applied in the capacitor manufacturing industry.
