Microwave Reticulation of Epoxy Resins Used for Single Layer Electric Insulations

AbstractThe main objective of these experiments is to identify the possibilities for proving a microwave technology for thermal reticulation of electric insulations deposited on metallic supports. To avoid the occurrence of phenomena that could affect the integrity of the microwave generator, the system has been equipped with a load for absorbing the residual power in microwaves. The charge placed in the applicator is made of a microwave-transparent plastic coil through which water circulates. The insulating material used during the experiments was P772 special tape impregnated in epoxy resin deposited on a metallic support through rolling. The quality of the electric insulation obtained by means of the microwave technology is better compared with the conventional methods.
