<p>Insulation gas (e.g. SF6 gas) filling an apparatus case is prevented from leaking to the outside of the apparatus case. A conduction member of an electric apparatus comprises an insulating bushing (11) provided, at the rear end portion thereof, with an opening (14) for receiving the end portion of a connection member (2), and an inner conductor (12) provided at the forward end portion of the bushing (11) airtightly to close the opening of the bushing (11). A flange member (12c) is provided to extend radially outward from the outer circumference of the inner conductor (12) and embedded in the bushing (11). The conduction member (1) of an electric apparatus is fixed airtightly to the inner wall of a case (C) for containing the electric apparatus, and the end portion of the connection member (2) is connected removably to the reception opening (14) constituting the conduction member (1) of an electric apparatus from the outside of the apparatus case (C). The connection member (2) comprises a pipe-shaped or columnar conductor, a rubberlike elastic insulator provided on the outer circumference of the conductor through an inner semiconductor layer (23), and an outer semiconductor layer (24) provided on the outer circumference of the insulator across the inlet of the reception opening (14).</p> |
