Abstract
A bushing, having an elongated conductor substantially encased in insulating material, which extends in sealing relationship through an aperture in a sealed enclosure encasing an electrical apparatus, comprising a conductor having two parts, a first generally cylindrical rod part which is permanently fixed at its proximal end to the electrical apparatus and which extends therefrom toward the aperture, and a second sleeve part having a generally annular passage disposed to circumferentially engage substantially all of the first rod part and thereby provide a conductive path therebetween; a one-piece insulator permanently attached to and substantially encasing the sleeve part of the conductor; means for threadably connecting the two parts of the conductor such that connection and disconnection can be accomplished from outside the enclosure, thereby enabling disconnection of the sleeve part and the insulator from the electrical apparatus without opening the enclosure; and means for sealing the junction of the two parts of the conductor so as to contain the environment within the enclosure.
