Patent number: 5729888Abstract: An integrated electrical system includes a first conductor for receiving current from power lines or other equipment. The conductor is coupled to a conventional vacuum switch for controlling flow of current through the system. A current collector coupled to the vacuum switch collects current from the vacuum switch. A second conductor coupled to the current collector delivers current to equipment or lines externally of the device. The components of the system are housed within an inner epoxy encapsulated within Polysil. The epoxy preferably has temperature characteristics which are similar to that of Polysil to prevent cracking due to temperature stress. At least one sensor may also be provided integrally with the components for detecting faults or for sensing general power line conditions. A preferred voltage sensor has resistive shielding for accurate sensing in adverse environments.Type: GrantFiled: June 7, 1995Date of Patent: March 24, 1998Assignee: Lindsey Manufacturing CompanyInventors: Abdelgawad Abdelgawad, Mun Seog Choi, Keith E.

Patent number: 4934114Abstract: Disclosed is a kit of low cost, light weight, corrosion resistant components, including a plurality of extruded members, certain ones of which components are factory preassembled into climbable and unclimbable tower units selected one of which are adapted to be rigidly connected end-to-end by overlapping couplings into a tower at an installation site to support a power line or other load. The couplings and the overlapping surfaces of the tower units have teeth that mesh to lock the couplings in place. The tower is specially suitable for erection in confined areas to heights in excess of one hundred feet to support power conductors. A number of components are selectively attachable to the tower in a wide variety of ways to support high tension insulators in suspension and/or cantilever fashion and to anchor guy cabling to the tower.Type: GrantFiled: January 28, 1988Date of Patent: June 19, 1990Assignee: Lindsey Mfg.

Patent number: 4823022Abstract: A line condition sensing device, e.g. a current transformer and/or a voltage transformer, is embedded in a pole mounted, power line supporting insulator to form an integral unit therewith. One end of the insulator carries a pole mounting base. The other end of the insulator carries a power line receiving clamp. The line condition sensing device is connected in parallel with a hot power line by taps to permit conditions to be monitored without cutting or dead ending the line. The device is installed on a hot line by opening the power line receiving clamp of the original insulator, holding the power line in spaced relationship from the original insulator while replacing it with the new insulator, resecuring the power line on the clamp of the new insulator, and then connecting the taps to the hot power line.Type: GrantFiled: June 22, 1988Date of Patent: April 18, 1989Assignee: Lindsey Manufacturing CompanyInventor: Keith E.

Patent number: 4247084Abstract: Stringing block threading apparatus for use in uncoupling a junction in a conductor hauling line and inserting a threading loop therein previously assembled through the throat of a stringing block. The hauling line is advanced along power line towers by a helicopter and the advance sections of this line are separably joined by a double ended coupling. This coupling is deposited into the threading apparatus atop each tower where it is automatically disconnected from the hauling line allowing enlargements on the released section ends to separate and become trapped in respective mating couplings at the opposite ends of the threading loop and the leading one of which is of the same double ended construction as the one deposited in the threading apparatus by helicopter. This coupling is deposited in the next threading apparatus for a repeat threading operation.Type: GrantFiled: January 15, 1979Date of Patent: January 27, 1981Inventors: Keith E. Lindsey, L. E. Lindsey
