ABSTRACT:
Inner conductors of isolated phase bus sections arranged end to end are joined by a multiplicity of longitudinally extending, annularly arrayed contact fingers which are biased radially inwardly against the conductors being joined with one end of each finger riding in a groove provided therefor on the exterior of one conductor and the other end of the finger being biased against the end of the next adjacent conductor to make slidable contact engagement therewith; a single dielectric shield surrounds both ends of the conductors and the contact fingers and is non-rigidly fastened at its longitudinal ends to the respective shells around each of the endwise adjacent conductors; springs extend between the shield and the fingers to bias the fingers against the conductors; the shield and finger arrangements permit the maximum width for the inner conductors enabling maximum quantities of contact fingers to be used and this arrangement also permits great misalignment between conductors, or tilting of one conductor with respect to the other and enables compensating for ambient condition caused contraction and expansion of the conductors themselves.
