ABSTRACT:
The invention concerns electrical hermetic penetrant structures, used for transfer of electrical energy through tight protections of nuclear stations, transport with nuclear reactors, tunnels of the underground, etc. Objective of the present invention is providing of long tightness of electrical penetrant structure due to increase of its stability to influence of electrochemical corrosion. The task in view is solved because of electrical hermetic penetrant structure, consisting of the metal case under pressure of gas, bushing insulators attached to the case through thin-walled transitive details and through bellows, and a monolithic current conducting core with the firm insulation, tightly installed inside of bushing insulators, characterized by that ceramic-metal covering of titan-trinitride with thickness of 8–30 microns is applied onto bellows surfaces.
