A bushing comprises an insulating body having a first body end portion, a second body end portion, and a body center portion connecting the first body end portion and the second body end portion, and a bushing conductor coaxially extending within and mechanically coupled to the insulating body. The bushing conductor includes a first connecting portion having a first end face at the first body end portion, a second connecting portion having a second end face at the second body end portion, and a center portion electrically and mechanically connecting the first connecting portion and the second connecting portion. The first connecting portion is elastically deformable with respect to the first body end portion along a radial direction and/or the second connecting portion is elastically deformable with respect to the second body end portion along the radial direction.
