高圧力が要求され、更に使用温度も従来になかったよう
な高温度、例えば封入液が水の場合１００℃程度の温度
がしばしば要求されるようになってきた。[Problems in the background art] In recent years, due to coordination with the usage conditions of pumps for sealing the filled liquid 3, the side-injected liquid 3 is required to have a high pressure of, for example, several to tens of atmospheres, and furthermore, the operating temperature has increased. However, higher temperatures than ever before, for example, temperatures of about 100° C. when the filled liquid is water, are now often required.

構造。(1) A frame that houses an electrical equipment main body and high-pressure fluid inside and has an opening that communicates the inside and outside, and an insulator that is provided in the opening. The high-pressure fluid generates an insulated conductor in which an outlet conductor of the electrical equipment main body supported by the insulator and a seal portion provided at a portion where the insulator and the opening are in contact are integrally formed. 2. An opening structure for an electrical device, in which the sealing portion is pressed against the inner surface of the opening of the frame by a pressing force in the external direction of the frame, thereby bringing the sealing portion into close contact with the inner surface of the frame. (2. The insulated conductor according to claim 1 is an outlet structure for an electrical device, characterized in that the insulator, the two-outlet conductor, and the seal portion are integrally molded with an insulating molding material.
