20150207305 | INSULATOR COVER WITH SECURING CLIP FOR ELECTRICAL DISTRIBUTION SYSTEMS - A dielectric cover system for an insulator supporting a high voltage conductor is molded to fit over the insulator to cover at least a top portion of the insulator and the conductor in contact with the insulator. A clip internal to the cover allows the cover to be freely placed over the insulator and then effectively restricts an inner diameter of the cover at a reduced diameter neck portion of the insulator, such that the clip blocks the cover from being lifted off the insulator and rotated about the insulator during high wind conditions. The clip is particularly effective where the conductor is supported in a side groove of the insulator, so the insulator and conductor form an asymmetric structure. | 07-23-2015 |
20150114678 | INSULATOR COVER FOR ELECTRICAL DISTRIBUTION SYSTEMS - A dielectric cover system for an insulator supporting a high voltage conductor is molded to fit over the insulator to cover at least a top portion of the insulator and the conductor in contact with the insulator. A bolt through the cover is inserted to a depth to engage a reduced-diameter neck area of the insulator to prevent the cover from being rotated about the insulator during a high wind condition. Other securing devices may instead be used that allow the cover to be freely placed over the insulator and then effectively restrict an inner diameter of the cover at a reduced diameter portion of the insulator, such that the securing device blocks the cover from being lifted off the insulator and rotated about the insulator. | 04-30-2015 |
20150107892 | ADJUSTABLE DOUBLE INSULATOR COVER FOR ELECTRICAL DISTRIBUTION SYSTEMS - An expandable dielectric cover system for a pair of insulators supporting a conductor includes a first insulator cover and a separate insulator cover. A sleeve covers portions of the first insulator cover and second insulator cover and covers the conductor between the two covers. The sleeve covers a variable length of the first insulator cover and second insulator cover to accommodate a wide range of separations between the two covers while still covering the conductor. Pivotable arms are connectable to the other sides of the covers for covering a length of the conductor extending away from the sleeve. | 04-23-2015 |
20140034380 | HIGH VOLTAGE CABLE AND INSULATOR SHIELD WITH FLEXIBLE ARM CONNECTOR - A plastic shield for a cable and insulator is described having a center section for covering the insulator. The center section has an opening at both its ends for the cable. Proximate each opening is a pivotable and bendable flange, where the flange pivots at one end of the flange and freely bends. An arm extends from each of the cable openings of the center section, and each arm covers the cable exiting the center section. Each arm is pivotally attached to the other end of the associated flange. The flange allows its associated arm to be moved over a wide range of horizontal and vertical angles (e.g., up to 45 degrees) and allows the arms to have a variable horizontal and vertical offset relative to the center line of the center section and insulator to accommodate a cable that is offset from the center line. | 02-06-2014 |
20130299230 | High Voltage Cable and Insulator Shield - A plastic shield for a cable and insulator is described having a center section for covering the insulator. The center section has an opening at both its ends for the cable. Proximate each opening is a pivotable flange, where the flange pivots at one end of the flange. An arm extends from each of the cable openings of the center section, and each arm covers the cable exiting the center section. Each arm is pivotally attached to the other end of the associated flange. The length of the flange will typically be about 2-3 inches. The flange allows its associated arm to be moved over a wide range of lateral angles (e.g., up to 45 degrees) and allows the arms to have a lateral offset relative to the center line of the center section and insulator to accommodate a cable that is offset from the center line. | 11-14-2013 |
20130264097 | Insulating Cover and Retaining Pin for High Voltage Electrical Transmission Structures - A plastic retaining pin for being inserted through a retaining hole in a high voltage insulating cover has an oval cross-section. The pin has a compressible nose, with the wide part of the nose being larger than the retaining hole. The nose has a relatively long front portion that expands out from the tip at about a 15 degree angle for easy insertion through the retaining hole. A back part of the nose is relatively short and has a relatively steep angle of about 45 degrees so as to require a higher pulling force to compress the nose when removing the pin from the hole. The other end of the pin has a grasping hole for receiving the hook of a hot stick. If the retaining hole is oval, the grasping hole is at a predetermined orientation with respect to the insulating structure to ease removal using a hot stick. | 10-10-2013 |
20120279778 | Wildlife Flashover Preventer for High Voltage Electrical Transmission Structures - A conventional grounded steel tower, or other structure, supports multiple wires (e.g., 6) carrying multi-phase high voltage electricity (e.g., >100 kV). Each wire is supported by a ceramic insulator connected to a horizontal arm of the structure, where an angled strut helps support the arm. There are usually three tiers of wires. The closest distance between a wire and ground is typically between the wire and an angled strut below the wire, where the angled strut helps support a lower-tier wire. A guard formed of a dielectric is affixed to and covers the lower portion of the steel strut as well as any steel that outward extends beyond the strut. The guard prevents flashover between a wire and the underlying grounded strut if a large bird perches on the guard, since the bird will not be grounded by the strut. | 11-08-2012 |
20100263302 | Wildlife Deterrent for High Voltage Supporting Members - A wildlife deterrent for a utility support structure member between two conductors includes a bracket for attachment to the supporting member, a center support piece with a variable height arm connector, and two adjustable arms pivotally attached to the arm connector. No tools are required for the adjustments or attachments. Since the effective lengths of the support and arms are adjustable, either by elongation or using different length parts, the same angle of the arms can be achieved no matter what the separation between the conductors, and the gap between the arms and the conductor can be optimal for both deterrence and flashover prevention. The different pieces forming the deterrent can be selected by the lineman to quickly build an optimal deterrent in the field. | 10-21-2010 |
