| 20080233786 | SEPARABLE LOADBREAK CONNECTOR AND SYSTEM - Separable loadbreak connectors include an interference element spaced about the contact tube that is configured to engage a portion of a connector piston. | 09-25-2008 |
| 20080261465 | Separable Insulated Connector System - Separable insulated connector systems for power distribution systems wherein the interfaces of the mating connectors are modified to reduce mating and separation force. | 10-23-2008 |
| 20080299818 | Jacket sleeve with grippable tabs for a cable connector - A jacket sleeve with grippable tabs provides protection to exposed portions of cable that are connected to an electrical connection. The jacket sleeve can be made as part of the electrical connector or may be connected subsequent to its creation through the use of glues or other adhesives. The jacket sleeve can be made of a material that is more pliable than the electrical connector, making it easier for a lineperson to place the sleeve over an exposed portion of cable. The jacket sleeve can include holes or slots either in the sleeve or in tabs that are attached to the sleeve. A lineperson can place one or more fingers into each hole or slot in order to get a better grip on the sleeve and pull the sleeve over the exposed portion of cable with less slippage and effort on the part of the lineperson. | 12-04-2008 |
| 20090100675 | Method for manufacturing a shield housing for a separable connector - A separable connector shield housing includes a layer of conductive material disposed at least partially around a layer of non-conductive material. The layers are molded together. For example, the conductive material can be overmolded around the non-conductive material, or the non-conductive material can be insert molded within the conductive material. The molding results in an easy to manufacture, single-component shield housing with reduced potential for air gaps and electrical discharge. The shield housing defines a channel within which at least a portion of a contact tube may be received. A contact element is disposed within the contact tube. The conductive material substantially surrounds the contact element. The non-conductive material can extend along an entire length of the contact tube and other components, or it may only extend partially along the contact tube. The non-conductive material can include an integral nose piece disposed along a nose end of the contact tube. | 04-23-2009 |

| 20090119899 | Method of Assembling a Vacuum Switchgear Assembly - 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. | 05-14-2009 |
| 20090255106 | Method of using an extender for a separable insulated connector - Removal of a conventional separable insulated connector from an electric power system often results in a shortened electric cable. An extender for a separable insulated connector enables the separable insulated connector to connect to a shortened cable. A conventional cable adapter is inserted into the extender, which includes a conductive connector for accepting the shortened cable and a conductive rod for carrying electric power from the shortened cable to the separable insulated connector. The extender also includes an inner semi-conductive layer that borders the conductive rod and compression connector, an outer semi-conductive layer, and a insulating layer between the two semi-conductive layers. The extender is inserted into a separable insulated connector, which is then connected to the electric power system. | 10-15-2009 |

| 20110151696 | Lockable Cable For Securing Fuse In A Loadbreak Elbow - A loadbreak elbow includes a sleeve having an upper portion defining a fuse housing and a lower portion defining a cable entrance. A shield housing is positioned within the upper portion and includes a first opening for receiving a cable connector and second opening in communication with the first opening for receiving a fuse. A fuse is positioned in the second opening of the shield housing and a fuse ferrule is threadably coupled to the cable connector in the first opening. The cable connector includes a retaining feature, and the shield housing includes a retaining means to engage the retaining feature so as to prevent the cable connector from rotating within the shield housing while the fuse ferrule is being coupled to the cable connector. | 06-23-2011 |
