Abstract: Vibration resistant cables containing a first conductor and a second conductor, each having a diameter d, are disclosed. The second conductor is twisted around the first conductor at a lay length between 3 feet and 6 feet to eliminate bagging of the vibration resistant cable during installation.
Abstract: A cable reel of the present disclosure can include two flanges and a central drum being independently rotatable from one another. The drum, which can be configured to receive a cable, can be mounted on an axle. The two flanges can be rotationally mounted on the axle at opposing distal ends of the axle. Bearings in the flanges can allow for a full rotation of the flanges about the axle.

Abstract: Disclosed is type THHN cable having a reduced surface coefficient of friction, and the method of manufacture thereof, in which the central conductor core and insulating layer are surrounded by a nylon sheath. A high viscosity, high molecular weight silicone based pulling lubricant for THHN cable, or alternatively, erucamide or stearyl erucamide for small THHN gauge wire, is incorporated, by alternate methods, with the nylon material from which the outer sheath is extruded, and is effective to reduce the required pulling force on the cable during installation.

Abstract: A rugged cable may be provided. The rugged cable may comprise a first layer, a second layer, and a third layer. The first layer may comprise fibers in which chain molecules comprising the fibers of the first layer are highly oriented along axis of the fibers of the first layer. The second layer may be around the first layer. The second layer may comprise metal. The third layer may be around the second layer. The third layer may comprise fibers in which chain molecules comprising the fibers of the third layer are highly oriented along axis of the fibers of the third layer.

Abstract: An improved pay-off assembly allowing cable loaded on a cable reel to be transported to an installation site and/or paid-off during a cable pull is described. The pay-off assembly may include one or more of lateral support braces that provide stability and strength to an A-frame structure supporting the cable reel; a reel lock assembly for securely holding the cable reel in place during transport and/or pay-off of the cable; an end cap assembly that prevents detachment from an arbor as the arbor and cable reel rotate during pay-off; a dog hole stop assembly that engages a “dog hole” in the cable reel to prevent the cable reel from rotating during transport; a braking system for controlling the rotational speed of the cable reel during pay-off; and a ground attachment assembly that allows an additional cable reel to be loaded for transport and/or pay-off of the cable.

Abstract: Electrical accessories and associated methods of use and manufacture are shown and described. In one example embodiment, a system includes a plurality of electrical junction boxes. Each electrical junction box includes at least one wall with a pair of spaced-apart holes, wherein the holes are sized and shaped to receive a pair of corresponding mounting devices. The system also includes at least one mounting bracket. The mounting bracket includes a pair of spaced-apart mounting devices, wherein the mounting devices are sized and shaped to protrude through the pair of corresponding spaced-apart holes in the plurality of electrical junction boxes. At least one of the plurality of electrical junction boxes is maintained in a relative stationary position with respect to the at least one bracket when the pair of spaced-apart mounting devices protrudes through the respective pair of spaced-apart holes in the wall of the at least one electrical junction box.

Abstract: Flexible indicia bearing labels are placed on armored electrical cable at spaced apart intervals while the cable is being moving continuously from an armoring station to a takeup reel or accumulator. A label dispenser places labels in a U shaped recess of a body which is moveable toward engagement with the cable. Opposed rollers fold one edge of the label over into engagement with the surface of the cable and the other edge of the label over onto itself in overlapping relationship. The cable is passed through a heat tunnel to shrink the labels into tight engagement with the cable. A controller monitors movement of the cable and controls actuators for applying and folding labels onto the cable at spaced apart intervals.
