Abstract

The present invention relates to a method for impregnating a porous material, which method comprises impregnating the insulation material with an impregnating fluid comprising an oil-like hydrocarbon mixture. The method is characterised in that the impregnation is performed in the presence of a tenside. The tenside is preferably a non-ionic tenside. The invention also relates to the using of the method for impregnating the insulation in an electric device, preferably a direct current cable.
