Abstract
Method and apparatus for forming a joint in a high voltage gas insulated electrical system wherein an outer spherical joint member surrounds an inner spherical joint member which is supported from only one of the inner housing conductors. The inner housing conductor which supports the inner sphere is supported where it extends into the outer housing sphere from a circular insulating member. The circulating insulating spacer and support is rigidly connected to a flanged opening formed on the outer housing sphere. The inner sphere which is rigidly supported is provided with a plurality of sliding contact openings for engaging other inner conductors of the additional bus sections to be joined. The outer spherical housing is formed from two hemispheres each of which has an opening formed therein. The plane defined by the opening into the hemisphere is transverse to the plane defined by the free ends of the hemisphere. Thus when the hemispheres are joined to form the outer housing sphere by relatively positioning the hemisphere angular variability can be obtained. That is, when the hemispheres are positioned to define a sphere if they are rotated relative to one another the angle, defin…
