Abstract:
A wedge deadend used to secure a cable is disclosed. The wedge deadend includes a single assembled frame comprising two plates. Two wedges between the plates grip a cable between them. A cam/bail retainer is included to align the wedges precisely.
Abstract:
An apparatus, called a wedge deadend, used to secure aerial fiber optic transmission lines or cables. The deadend and secured cable can effectively be attached to support structures such as poles or towers. The wedge deadend has a single assembled frame with an attaching cable for mounting to the support structure and two wedges that slide into the frame. The frame consists of two parallel plates. Each plate has two slots that are tapered and angled toward one another. The wedges are similarly tapered enabling them to be interlocked with the side plates. Both wedges also have a groove that is sized and textured to grip a specified cable. The wedges can be designed to compress the encased cable evenly along the entire contact surface of the wedge, or with varying force along such surface.
Abstract:
A method of fusing cables and a dead end assembly and a cable are provided. A joint assembly for fusing cables and a dead end fusing assembly for fusing a cable and a forge assembly are provided. The method includes cutting back strands of a cable, exposing the core; inserting the core of cables into a core grip; positioning the joint assembly over the core grip within certain marked sections of the cables; wrapping the joint assembly with one wrap of detonation cord; securing a detonator to the detonation cord explosive charge and detonating the detonator, such that the core grip fuses the cables together.

Abstract:
A clamp with a first clamp halve with a hinge portion and a first opening for a fastener; a second clamp halve, with a hinge portion and a first opening for a fastener; a cable opening; and a hinge device for connecting the two hinge portions. The clamp may also include a first clamp halve with a second opening for a closing insert.

Abstract:
An easily installable, robust device capable of securing and supporting cable even under extreme weather and loading conditions. The device supports cable during and after stringing of the cable. The device is easily adaptable to accommodate a large range of cable diameters and can be mounted to a variety of support structures.The device includes a body and cap formed via die casting. A non-machined hinge mechanism that is die cast as a portion of both the body and the cap connects the same and allows the device to be mounted as a single unit to a support structure. A two piece grooved elastomer bushing seats in the body and cap to surround and cushion the cable extending through the device. By altering the size of the grooves of the bushing, various diameter cable can be accommodated.Side walls having windows formed on the body of the trunion help facilitate distribution of the load of the cable. The tunion body also includes a non-threaded hole that may be used in conjunction with a fastener such as a lag bolt or a double arming bolt to secure the trunion to a support structure.

Abstract:
A connector assembly for use in transmission line installations. An elongated steel tube is provided and an aluminum sleeve is axially inserted into the tube and exhibits a rate of extrusion greater than the tube. A current carrying cable has a plurality of outer strands and a central extending plurality of inner strands which insert within the sleeve. The tube is subjected to a mechanically compressing and area reducing procedure such that the sleeve extrudes at a rate greater than the tube and the aluminum material associated with the sleeve fills irregularities existing between the inner strands. The sleeve also establishes stress relief between the wire strands and the tube. An aluminum outer tubular body is slidably engaged over the assembled tube and sleeve and is mechanically compressed at specified locations in order to secure about the outer strands of the cable.
Abstract:
An apparatus, called a wedge deadend, used to secure aerial fiber optic transmission lines or cables. The deadend and secured cable can effectively be attached to support structures such as poles or towers. The wedge deadend has a body that consists of multiple hinged segments that are opened and closed to load and access cable. The body accommodates multiple interlocking wedges which track the inside of the body and interlock with each other via teeth. Both the body segments and wedges are tapered such that one end of the body when closed is angled inwardly. When the body is closed, the wedges form an opening that is sized and textured to grip cables of various range diameters. The wedges are designed to compress the encased cable evenly along the entire contact surface of the cable.
