A switching device has an improved fastening arrangement to provide a hermet ic and gas-tight, secure joint where the electrical insulating bushing (51,52) mates with a circuit interrupter tank (50). The fastening arrangement utiliz es a plurality of fasteners (60) that are inserted laterally, or more preferabl y, substantially perpendicular to the central axis of the insulating bushing, a nd spaced equidistantly around the perimeter of the insulating bushing (51,52). The switching device also discloses a novel external housing (64) arrangemen t to enclose externally mounted circuit transformers (61) that has an enhanced profile and affords easy accessibility to the transformers (61) in the field .
