  • Patent number: 10277022
    Abstract: A cable suspension may allow a cable to be pivoted about a pivot axis that passes through a thickness of a cable. A bend radius of the cable entering and exiting the cable suspension may be increased and/or the degree of bend by a cable entering and exiting the cable support may be decreased. The cable may comprise insulated electrical cables, non-insulated electrical cables (e.g., conductors), shielded cables, non-electrical signal cables (e.g., optical cables), and/or assemblies thereof.

  • Patent number: 10246253
    Abstract: In a fluid reservoir tank such as an oil tank, the metal roof floats. The American Petroleum Institute (API) Recommended Practice (RP) number 545 requires a floating roof to tank resistance of less than 30 milli-ohms. The improved cable system uses a preferred aluminum braided cable to provide low resistance combined with resistance to sour fluids. Prior art used copper and tinned copper braided cables. The new reel is factory pre-assembled and tensioned using a new cable guide with a cable stop bar which stops a cable stop attached near the end of the (approximately 80 foot) cable. A new spring assembly increased tension and extends cable life by minimizing slack in the cable.

  • Patent number: 10199150
    Abstract: The power transmission tower mounted series injection transformer (TMIT) injects impedance and/or voltage on a transmission tower power line. A tension bearing tower uses vertical and horizontal insulators to support and stabilize the TMIT. The TMIT can be much heavier than a transformer device clamped to the high-voltage transmission line. The TMIT is connected in series with the tension bearing tower's jumper allowing it to use a multi-turn transformer. By operating at the line voltage potential, the TMIT does not require the large bushings and oil drums used by sub-station injection transformers.

  • Patent number: 6096970
    Abstract: A clamp for an overhead line including a clamp body in which a first gripping groove for gripping the overhead line is formed; a clamp cap in which a second gripping groove for gripping the overhead line is formed and which is pivotably attached to the clamp body via a hinge unit; a fastening unit for fastening the clamp body and clamp cap in a manner enabling free opening and closing so that the overhead line is affixed between the first and second gripping grooves so as to be unable to move in an axial direction at the pivot position of the final fastening state; and an expansion unit for causing the clamp cap to stop at a position where it is forcibly kept open by a predetermined clearance from the clamp body against a fastening force given by the fastening unit so that the clamp body and the clamp cap are not located at the pivot position of the final fastening state and in addition so that a clearance is formed between the first and second gripping grooves and the overhead line and a method for attachmen

  • Patent number: 6057508
    Abstract: The invention uses one or more scissor devices, or disks, or cogs such that the axial thermal expansion of a coupling member is amplified such that this amplified movement is used to automatically mitigate the sag of a suspended line; the same ambient temperature change that causes the line to sag concomitantly causes the coupling member to expand, so that sag mitigation is passive and automatic. The invention includes a device for automatically mitigating thermal expansion sag in suspended lines comprising a coupling member or actuator rod (140) that expands axially with increasing temperature and that is mounted between the proximal arms (110) of a reverse-scissor component (60), said reverse-scissor component having first arms (70) and second arms (80) and a hinge (90) and the arms having distal ends (100) longer than proximal ends (110). The distal arms are insulated by insulators (130). The reverse hinge acts such that when the proximal arms are moved apart, the distal arms are brought together.

  • Patent number: 5789701
    Abstract: A drop cable arrangement in which a carried line (9) is supported by a strength member (3), the carried line being attached to the strength member via a tubular member (7) that is a sufficiently loose fit around the strength member to permit relative longitudinal movement therebetween. In the event of additional loading on the drop cable the strength member extends due to the increased tension, but this tension is not transferred to the carried line due to the permitted relative movement of the tubular member and strength member.

  • Patent number: 5308923
    Abstract: The cover and base of the enclosure of the assembly are releasably connected by latches and flanges integral with the cover and base. A mounting bracket facilitates mounting of the assembly upon a telephone pole or other exposed static structure. Vertically spaced upper and lower cable strain-relieving members underlie each cable passageway of the base of the enclosure. Each strain-relieving member is of generally u-shaped configuration. The open ends of the upper and lower strain-relieving members face in different directions. Each pair of the strain-relieving members collectively extends about the entire circumference of a cable engaged thereby.

  • Patent number: 5036162
    Abstract: A mount for securing a load, for example a strut insulator, to a stationary support has a pair of end parts one of which is fixed to the load and the other of which is fixed to the support and a pair of respective intermediate parts. Respective end pivots connect the intermediate parts to the end parts for pivoting thereon about respective axes that are perpendicular to each other and a central pivot connects the intermediate parts to each other for relative pivoting about a center axis lying substantially perpendicular to the end axes. One of these end axes is at least generally horizontal and at least generally aligned with the load.

  • Patent number: 4565038
    Abstract: A guy yoke for use in a guyed structure terminate two support guys coupled to said structure and to transfer loads entered on said supported guys to anchor means, said guy yokes includes two arms pivotally coupled to an anchor plate at one end and coupled to guy wires at the other end. A spreader arm is coupled to the arms to maintain them in a fixed position for forces transmitted by the guy lines which are below a predetermined level. The spreader arm is coupled to the two arms by shear bolts or pins. When the forces transmitted to the yoke are at or exceed the predetermined level, one or both of the shear bolts or pins is severed permitting the two arms to swing toward each other and thereby add effective length to the guying.
