An electrical bushing which contains a pressurized gas as the main insulation and which contains a metallic shield electrode therein near the grounded end of the tubular outer insulator for control of the voltage distribution, also includes a solid insulating body which is made of a material having a higher permittivity than the insulating gas, thus enabling the bushing to have a smaller diameter. The metallic shield electrode is at least partially embedded in the insulating body. The insulating body includes an upper field-controlling portion in the space between the tubular outer insulator and the central current conductor which includes an inner side that extends towards the conductor to form a tapered annular space, most of the upper portion being located beyond the metallic shield electrode with respect to the grounded end of the tubular insulator.
