Abstract: Insulated vacuum switchgear and active switchgear elements therefor are provided with a rigid support structure mechanically isolating a vacuum insulator from axial loads in use without reinforcing or insulating encapsulations. At least one of the elastomeric insulating housing and the support structure directly contacts an outer surface of the insulator. Systems and methods for assembling the switchgear are also provided.

Abstract: An electrical connector includes a sleeve defining an axis and a contact assembly inserted in the sleeve, the contact assembly including pieces that move axially relative to one another during a fault close operation. An interface between the sleeve and the contact assembly is configured to permit replacement of the contact assembly without replacing the sleeve.

Abstract: An installation tool for mounting a loadbreak reducing tap plug in a high voltage "T"-type connector of the type including a cable connector having a threaded opening, the plug having a threaded end adapted to be mounted in the threaded opening of the cable connector and a threaded bolt extending through the threaded end of the plug, the threaded bolt having a wrenching opening and being rotated by a wrenching tool for connecting the plug to a bushing, the installation tool comprising a shaft having a threaded end corresponding to the threaded opening in the connector and a threaded opening corresponding to the threaded bolt, whereby the threaded end of the installation tool can be mounted in the threaded opening in the connector, the threaded bolt can be mounted in the threaded opening in the installation tool, and the threaded end of the plug can be drawn into alignment with the threaded opening in the connector when the installation tool is backed out of the threaded opening in the connector.
