  • Patent number: 10374408
    Abstract: A ground rod cap is provided. The cap includes a body that fits around a ground rod, ground rod clamp and ground wire at their point of connection. The body retains a filler material within an internal cavity. In some embodiments, a portion of the body acts as a barrier to retain the filler material. In some such embodiments, the filler material is positioned within the body prior to installation of the cap on the ground rod connection components. In some embodiments, the filler material is located in an airtight cavity until installation. In some such embodiments, a shrink-wrap material is placed around the body to make the cavity airtight. In other embodiments, the filler material is retained within at least a portion of the cap by an internal barrier that breaks as the cap is installed to allow the filler material to flow around the components.

  • Patent number: 6204445
    Abstract: A communications cable is provided having a support strand and at least one coaxial cable helically wound around the support strand. The coaxial cable includes an inner conductor, a dielectric surrounding the inner conductor, an outer tubular metallic sheath surrounding the dielectric, and optionally a protective jacket surrounding the metallic sheath. The communications cable is manufactured such that the ratio of the length of coaxial cable to the length of support strand is between about 1.005 and 1.015. The communications cable is also preferably wound around the support strand using a varying lay length thereby minimizing signal loss due to cable damage. The communications cable of the invention is especially suitable for aerial installation and may be installed in one pass, without the need to form expansion loops in the coaxial cable.

  • Patent number: 6127626
    Abstract: The invention concerns a method of installing a telecommunication cable (3) on a supporting cable (1), particularly on a ground or phase cable of a high voltage overhead line, whereby the telecommunication cable (3) is laid along the supporting cable (1) and is attached thereto in undulating form with the help of attaching elements (5; 11; 13; 15). This arrangement makes it possible to make repairs in a simple way on the supporting cable (1) and the telecommunication cable (3).

  • Patent number: 5897081
    Abstract: A method of replacing an existing telephone pole having a terminal box mounted thereto is disclosed. The terminal box is dismounted from the existing telephone pole. The terminal box is then permanently suspended from at least one overhead cable. A new telephone pole is installed, typically at some distance from the existing telephone pole. The existing telephone pole is then removed. A rigid suspension bracket is usable in the method for suspending the terminal box from the overhead cable. The terminal box is suspended in approximately the same location as the terminal box was mounted to the existing telephone pole. This reduces the stress on a splice and eliminates the need to recondition the splice and replace the terminal box.

  • 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: 5461200
    Abstract: Long flexible members such as hoses, electric cords and cables tend to be springy and elastic. They are not easily coiled and stored. They tend to straighten out when bent into a desired shape. They tend to tangle and interfere with operations. The invention incorporates an elongate wire element running parallel to the long axis of the flexible member. The wire element is encased in the covering of the flexible member. The wire element is a conformable shape-retaining material such as a compliant soft iron or steel. It renders the entire member shape-retaining so that it may be conveniently coiled for storage or positioned for use. An embodiment for retrofitting an existing flexible member provides the wire element encased in a covering which wraps around a flexible member and then seals closed to form a shape retaining sleeve about the member.
