Abstract
A cable adapter that is operable to electrically couple an existing switchgear cable used for old switchgear to a connection location on new switchgear. The adapter includes an elbow portion that is configured to be electrically coupled to a connector for the switchgear cable and an extension portion that is electrically coupled to the elbow portion. The adapter also includes a cylindrical connection portion electrically coupled to the extension portion and being configured to be electrically coupled to the new switchgear at the proper location. In one embodiment, the elbow portion, the extension portion and the connection portion combine as a single piece member including an internal conductor, a dielectric insulation rubber layer covering the internal conductor and an outer semi-conductive rubber layer covering the insulation layer, where the rubber layers are molded over the conductor.
