Abstract:
The invention relates to an anchoring device (1), including a body (2) intended for receiving a cable (32) and having an inlet area (14) and an outlet area (15) for the cable, and a means (21) for attaching the body to the mounting. The cable, which comprises at least one optical fibre (33) in a sheath (34), is wound by at least one turn around a substantially cylindrical winding wall (5) belonging to a drum (4). The body includes a means (19) for supporting a portion of the cable, said means being arranged so as to prevent the sliding of said portion of the cable without crushing said cable, in order to form a leader for holding the cable and to enable said cable (32) to be locked relative to the body (2) as a result of the winding of the cable around the winding wall (5).
Abstract:
An apparatus for connecting two pairs of conductors (306, 308) and one pair of ground wires (904, 906) and for allowing separation of the same upon the application of a tensional force upon at least one of the conductors or ground wires. The apparatus comprises two plates (102, 104) that each defines three holes configured to receive two conductors and a ground wire, wherein the plates are positioned adjacent to each other such that the respective holes in each plate are aligned such that the conductors and ground wires coming from each plate would be in physical contact. Three connectors (400, 500) hold the plates together. The first two connectors (500) are configured to release the plates upon the application of a tensional force on the conductors or ground wires before the third connector (400) releases the plates, thereby separating the conductors before separating the ground wires.

Abstract:
A method of installing a fibre optic cable (10) upon an overhead power line structure, the overhead power line structure including an overhead power line support (60)and an overhead power line (90) carried by the overhead power line support (60), the method comprising the steps of passing an end of the fibre optic cable (10) through a bore formed in an insulator (120); positioning the insulator (120) at an installation location adjacent to the overhead power line support (60) with the fibre optic cable (10) located within the bore in the insulator (120); bonding the insulator (120) in place once positioned in the said installation location; connecting the insulator (120) to a first end of a conductive carrier (160); and connecting a second end of the conductive carrier (160) to the overhead power line (90) such that the fibre optic cable (10) is supported by the conductive carrier (160) and the insulator (120) as it passes from a first side of the overhead power line support (60) to a second side thereof.
Abstract:
Methods for selecting a conductor configuration of an overhead power transmission line tension section between two dead-end towers when the conductor configuration includes at least two different types of conductors. Geographical profile information and overhead power transmission line preferences are used along with predetermined selection rules when selecting the appropriate conductor configuration. Some examples of overhead power transmission line preferences include electrical characteristics and conductor sag between towers, while examples of selection rules include conductor costs and conductor tension.
Abstract:
A method is provided for controlling the sagging of a power transmission cable hang between two towers. The cable has a first supporting portion and a second conductive portion. The method includes a first act of mounting the cable between the two towers, such that when mounted between the towers the cable has a cable load. The method further includes a second act of stretching the first portion to have a cable sag less than a desired sag, a third act of releasing at least some of the tension to obtain the desired sag, and a fourth act calculating a load magnitude carried by the first portion. If the load magnitude is less than a desired load magnitude the method includes repeating the second, third and fourth acts until the load magnitude is at the desired level.
