Abstract: A connector is provided for tensioning a guy line and connecting the guy line to a ground anchor or a tower. The connector may include a first body and a second body connected together by two or more threaded rods. The first body is connected to the ground anchor or the tower. The second body has a tapered cavity extending therethrough. The guy line extends through the tapered cavity, and wedges with a first and second inner arcuate surface that are vertically offset from one another are pushed into the tapered cavity. The first arcuate inner surface and the second arcuate inner surface may grip the guy line after the wedges have been pushed into the tapered cavity, while the vertical offsetting of the second arcuate inner surface reduces that stress on the guy line at an end of wedges. The first and second bodies may be drawn toward each other to tension the guy line.

Abstract: An isolation ground switch has a housing having a front housing portion and a back housing portion defining a housing cavity therebetween. A conductive switch plate is positioned in the housing cavity and rotatable between a closed position and an open position. A plurality of termination studs are mounted to the front housing portion, each termination stud having a conductive projection extending into the housing cavity.

Abstract: Interchangeable inserts are disclosed for use in enclosures, such as underground enclosures. The interchangeable inserts include insert bodies that are configured to house stand-alone nuts and nuts contained within removable trays.

Abstract: Enclosures are disclosed for use in underground applications. The enclosures include walls with end portions that are angled outward with respect to a middle of the wall such that the enclosures can be stacked on top of one another despite a draft angle of the walls. The bottom corners of the enclosures are aligned with a top surface of the enclosure to allow stacking. The enclosures include an opening in the bottom such that when multiple enclosures are stacked on top of one another, the enclosures for a single larger enclosure that can be used in underground applications.

Abstract: The present disclosure provides a fitting for a power transmission system. The fitting may include a first end configured to couple to an end of an insulator, a second end configured to couple to a power line, a collar located between the first end and the second end, and a neck located between the collar and the first end. An outer diameter of the collar may be greater than an outer diameter of the neck. A power transmission system with a fitting and corona ring assembly is also provided.

Abstract: One general aspect of the present disclosure includes an endcap for a crossarm. The endcap may have a base portion with a surface configured to face a cavity of a crossarm, a hub extending from the surface and configured to receive a fastening element, a gusset element coupled to the hub, and a brace element. The brace element may be configured to contact an inner wall of the crossarm. The inner wall may at least partially define the cavity. The gusset element may be configured to provide an expansion force to the brace element when the fastening element is received by the hub.

Abstract: The present disclosure relates to a mounting base for a crossarm and the crossarm. The mounting base may include a front-facing fastening surface, a rear-facing surface, and an opening formed between the front-facing fastening surface and the rear-facing surface, where the opening comprises a generally reverse L-Shaped geometry that extends through an entire width of the mounting base. The crossarm may include a first section and a second section that are oriented perpendicularly to each other, where the first section and second section are composed of composite material that contains a plurality of fibers within the composite material.

Abstract: The present disclosure provides a ground roller assembly for grounding electrical current induced in a conductor during installation of high power transmission lines. The ground roller assembly may include a mounting bracket having a plurality of pivot points spaced away from a mounting aperture, and an integrally formed tongue projecting outwardly away from an upper edge of the mounting bracket. A support arm may be coupled to one of the plurality of pivot points positioned proximate to a side edge of the mounting bracket.

The fitting may include a first end configured to couple to an end of an insulator, a second end configured to couple to a power line, a collar located between the first end and the second end, and a neck located between the collar and the first end. An outer diameter of the collar may be greater than an outer diameter of the neck. A power transmission system with a fitting and corona ring assembly is also provided.

Abstract: The present disclosure provides a stringing block. The stringing block may include a sheave with a circumferential groove with a pair of opposed walls. The opposed walls may extend away from the base of the groove to a flair point at a first angle. The opposed walls may extend away from the flair point to a rim at a second angle that is less than the first angle.

Abstract: Embodiments disclosed herein provide a connector and a method of using a connector. A connector for joining a cable with an anchor comprises a first end, a second end and a spacer extending between the first end and the second end. An opening is disposed at the first end. The opening has a configuration that mirrors a configuration of the anchor. A guying portion for joining the cable to the connector is disposed at the second end. An extension is disposed adjacent the spacer for facilitating juncture of the cable and the connector. In a method, the anchor is applied to a support surface and the first end and the anchor are joined. A tool that moves the cable in proximity to the guying portion is connected with the extension. The tool is activated to bring the cable closer to the guying portion. A portion of the cable is inserted into the guying portion for joining the cable to the connector. A further connector comprises a first end and a second end.

Abstract: A method and arrangement is provided to form a gas-tight joint between two housing portions, e.g. between an end flange and a tubular pole-unit housing for a circuit interrupter or an insulating support column. The joint is formed via a heat-shrink process to provide an interference fit. The housing is provided with grooves to retrain adhesive during the assembly process.
