Abstract

A high voltage insulator bushing is formed of wound insulating foils and is provided with conductive parts which are at different electric potentials and with a wound insulator body arranged between the conductive parts. The wound insulator body contains layers of an embossed insulating foil which consists of a plastic material which shrinks above a predetermined temperature. The embossed insulating foil is subjected to a thermal shrinking treatment prior to being wound as part of the insulator body. Such preshrinking prevents further shrinkage which would occur when the high voltage bushing is operated. Smooth insulating foil may be wound as part of the insulator body so as to be interposed between the layers of the embossed insulating foil. The gaps and voids which are formed between the layers of insulating foils caused by the irregular surface of the embossed insulating foil are filled with an insulating medium.
