    • A method for manufacture of an electric device having at least one conductor and a porous, fibrous and/or laminated electrically insulating dielectric system comprising a solid electrically insulating part impregnated with a dielectric fluid and a porous, fibrous and/or laminated body for use in an electric device produced with the method. The method comprises the steps of: providing a conductor and a porous, fibrous and/or laminated structure of a solid electrically insulating material associated with each other, pretreating the porous, fibrous and/or laminated body with a gelling additive such that the body comprises the gelling additive which imparts a high viscosity and elasticity to the fluid at conditions for which the device is designed to operate under, impregnating the pretreated body comprising the gelling additive with the dielectric fluid, wherein the gelling additive upon impregnation is brought into contact with the dielectric fluid and the gelling additive, at least in part, is dissolved by the fluid such that following the impregnation the dielectric fluid is gelled.
    • 一种用于制造具有至少一个导体和多孔,纤维和/或层压的电绝缘介电系统的电气装置的方法,其包括浸渍有介电流体的固体电绝缘部分和多孔,纤维和/或层压体,用于 使用该方法制造的电子装置。 该方法包括以下步骤:提供彼此相关联的固体电绝缘材料的导体和多孔,纤维和/或层压结构,用胶凝添加剂预处理多孔,纤维和/或层压体,使得主体包括 所述胶凝添加剂在所述装置被设计为在其下操作的条件下赋予所述流体高粘度和弹性,将包含所述胶凝添加剂的预处理体浸渍在所述介电流体中,其中所述胶凝添加剂在浸渍时与 介电流体和胶凝添加剂至少部分地被流体溶解,使得在浸渍之后,介电流体被凝胶化。
