Breakaway connector for drop/aerial/messengered coaxial cables
A breakaway coaxial cable connector includes a first conductive body configured to engage a first cable, and a second conductive body configured to engage a second cable. The first conductive body and the second conductive body are configured to be selectively coupled to each other so as to maintain electrical connectivity between the first cable and the second cable during operation of the connector when a first tension force below a predetermined threshold level is applied between the first cable and the second cable. The first conductive body and the second conductive body are configured to be selectively de-coupled from each other so as to interrupt electrical connectivity between the first cable and the second cable during operation of the connector when a second tension force above the predetermined threshold level is applied between the first cable and the second cable.
Apparatuses, systems and methods for determining effective wind speed
Systems and methods for determining an effective wind speed are disclosed. A system includes a first detector, a second detector and a processing unit. The first detector includes a heated temperature-sensing element having a heater and a first temperature sensor, and a first housing at least partially housing the heated temperature-sensing element. The second detector includes a non-heated temperature-sensing element having a second temperature sensor, a second housing at least partially housing the non-heated temperature-sensing element. The processing unit can be adapted to determine the effective wind speed according to a temperature at the heated temperature-sensing element, a temperature at the non-heated temperature-sensing element, and/or a difference between these temperatures and in accordance with an algorithm or table of values. The heated and non-heated temperature-sensing elements and their respective first housing and second housing are collinear, proximal and parallel to the conductor, and protected from precipitation by a shield.
JUMPER INSULATOR
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.

BUFFERING APPARATUS FOR MESSENGERED CABLES
A tensile-force buffering apparatus interposes a physical structure and a drop clamp having a messenger of an input drop cable secured thereto. The tensile-force buffering apparatus includes an outer housing defining an elongate inner cavity and a retainer, and a spring-strut assembly. The spring-strut assembly includes a central shaft, a retention member at a first end of the central shaft, and a coil spring disposed about the central shaft. The spring-strut assembly is received in the cavity of the outer housing, and the retention member is held by the retainer while a load compressing the coil spring is less than a predetermined threshold load. The retention member is released from the outer housing when the load compressing the coil spring reaches the predetermined threshold load, thereby effecting separation of the spring-strut assembly from the outer housing.

Shear Pin Bracket for Aerial Cable System
An apparatus for retaining a wire safely above ground in an overhead power distribution system that also prevents damage to a support structure caused by an object falling on the wire is disclosed herein. The apparatus may comprise a mounting base configured to be affixed to a support structure and a bracket arm configured to support a wire and rotatably engage the mounting base. The mounting base and the bracket arm may each include a set of apertures configured to receive a pivoting pin and a set of apertures configured to receive a shear pin. The bracket arm may be affixed to the mounting base in a horizontal position relative to the mounting base when the pivoting pin and shear pin are inserted into their corresponding apertures. The bracket arm rotates downward, pivoting around the pivoting pin, when the shear pin breaks due to impact on the wire.
