PURPOSE:To support a high-tension lead wire securely and easily and also to improve assembling precision of an insulating barrier on the bottom of a high-tension bushing by supporting a high-tension lead wire, an insulator for the high-tension lead wire and a shield in oil of the bushing with insulating tubes. CONSTITUTION:Insulating tubes 6a-6c are arranged concentrically to a high- tension bushing 4, formed thick enough to support a high-tension lead wire 5 and a shield 4a in oil and fixed with a supporting insulator 7 at the bottom. There is therefore no necessity for using a large member like column, lead support, etc. at the bottom of the high-tension bushing 4, and a dielectric breakdown to a core 1 or the wall of a tank 3 through these insulators can be prevented. Then in a relative position, the shield 4a in oil, the high-tension lead wire 5 and a barrier 10 can easily be kept separated from the high-tension bushing 4 which is easy to get out of position due to assembling precision and manufacturing error of the tank 3, and thus the assembling precision can be improved. |
