To provide a dry air terminal connection part which adopts insulating structure of a dry tape, without using insulating oil and whose insulating performance is stabilized.
An evaporation pipe 8, through which an insulating gas can be permeated, is installed at the inside of an insulating pipe 5 into which an insulating gas is filled and which is maintained under a positive pressure. Consequently, the insulating gas inside the insulating pipe is always maintained under a positive pressure, and the insulating performance of this dry air terminal connection part is stabilized and ensured. It is preferable to install a plastic permeation plate at the evaporation pipe 8. As a plastic material, polyethylene, nylon, Teflon(R), silicone rubber, EPR or the like are suitable. A liquid, gaseous or solid insulating substance is filled into the evaporation pipe. In this case, when the liquid or solid insulating substance is used, it is made to pass through as a gasified insulating gas.
