Abstract:
A cable spacer includes first and second angle arms each having a cable engaging end at one end and a flat tab portion at an opposite end having a connecting tab and an aperture to connect the arms to each other. An insulator extends between and connects the angle arms at their respective connecting tabs. The insulator has a non-conductive core. The angle arms and insulator mounted to each other define a spacer plane. A bottom arm is mounted to and depends from insulator. The bottom arm is mounted to the insulator to sway into and out of the spacer plane. A clamp secures the cable spacer to a messenger and includes upper and lower clamp portions. The upper clamp portion mounts to the messenger and the lower clamp portion mounts to cable spacer angle arms. The lower clamp portion is rotatable relative to the upper clamp portion.

Abstract:
An impact-absorbing wire and/or cable fixture, system, and related methods are disclosed. The impact-absorbing wire fixture apparatus includes a substantially rigid bracket having at least a first arm and a second arm, wherein the first arm is connectable to a utility support structure. A twisted portion is positioned within the second arm, wherein the twisted portion is at least a 90° rotation of the second arm, wherein the twisted portion of the second arm has a width that exceeds a thickness. A fixturing portion is positioned at a distal end of the second arm.
Abstract:
A conductor cover apparatus for use with an overhead electrical transmission and distribution system and related methods is provided. The conductor cover apparatus has a center cover member. At least one arm connector is formed on the center cover member, the at least one arm connector having an opening and a first hole positioned between a first external side and a second external side of the at least one arm connector. An extension arm is positioned at least partially interior of the first and second external sides of the at least one arm connector. At least one pin is removably connecting the extension arm to the at least one arm connector, wherein the at least one pin is positioned through the first hole of the at least one arm connector and a first arm hole within the extension arm.

Abstract:
An aerial roller spacer apparatus and related methods thereto are provided. The aerial roller spacer apparatus includes a spacer body. At least one saddle is formed on the spacer body. A spacer arm is connected to the spacer body at a first end, wherein the spacer arm extends away from the spacer body. A roller assembly is positioned proximate to a second end of the spacer arm, wherein the roller assembly has two rotatable roller halves that are removably engagable with one another with at least one fastener. A messenger groove is formed between the two rotatable roller halves.
Abstract:
A monitoring system is disclosed herein that is configured to utilize a distributed sensing system to monitor both a cable and cable accessories included within a cable circuit. In various embodiments, the monitoring system may include a distributed sensing system and one or more cable accessory wrap assemblies. The distributed sensing system may include a distributed sensing fiber following (or integrated into) the cable and connected to a cable accessory wrap assembly for each of the one or more cable accessories in-line with cable. In various embodiments, each cable accessory wrap assembly may comprise a cable wrap embedded with a distributed sensing fiber. The distributing sensing fiber of a cable accessory wrap assembly may be configured to provide measurements to distributed sensing system indicating that an anomaly event occurred at a given cable accessory.
Abstract:
In general, aspects of this invention relate to electrical cables and, in particular, to a cable with electromagnetic and/or anti-ballistic shielding. According to one aspect, a cable may comprise: a conductor; a continuous metallic sheath surrounding the conductor; and a supplemental sheath layer surrounding the metallic sheath. According to another aspect, a cable may comprise: a conductor; an armor layer surrounding the conductor; a fabric layer surrounding the conductor; and a polymer layer surrounding the conductor. According to yet another aspect, a cable may comprise: a conductor; an inner synthetic strength member surrounding the conductor; a polymer compound positioned between the conductor and the inner synthetic strength member; a polymer layer surrounding the inner synthetic strength member; an armor layer surrounding the polymer layer; an outer synthetic strength member surrounding the armor layer; and a polyolefin layer surrounding the outer synthetic strength member.
