Patent number: 8844905Abstract: Pulling eyes are provided with an integrated lug for electrically coupling conductors or cables to terminating equipment. The pulling eyes may include body portions that define interior cavities that are sized to snugly engage a bare metal portion of the conductors or cables. The body portions are sized to be deformably crimped onto the bare metal portions of the conductors or cables. The pulling eyes may also include head portions joined to the body portions, with the head portions are assembled to pulling ropes or cables for installing the conductors or cables. The pulling eyes may further include integrated lugs electrically attached or coupled to the body portions and configured to electrically couple the conductor to terminating equipment.Type: GrantFiled: January 17, 2011Date of Patent: September 30, 2014Assignee: Southwire Company, LLCInventors: John R. Carlson, David Brian McCardel, David A. Cooper

Patent number: 8701277Abstract: Disclosed is a method of manufacturing a finished cable by a process directed to reduce the amount of force required to install the cable. The process involves the extrusion of the cable's outer sheath and the incorporation of a pulling lubricant in connection with, and prior to the completion of, the extrusion to reduce the sheath's surface coefficient of friction as well as reduce the required force to pull the cable for installation. The conductor core is coated with an extruded plastic material with which an appropriate (in amount and type) pulling lubricant is initially combined with the plastic material prior to the formation of the sheath and in which the sheathed conductor core is thereafter cooled, the lubricant either migrating to and/or permeating the sheath to be available at the surface of the sheath at the time of the cable's installation.Type: GrantFiled: July 3, 2009Date of Patent: April 22, 2014Assignee: Southwire CompanyInventors: Randy D. Kummer, David Reece, Mark D. Dixon, John R. Carlson, Hai Lam, Philip Sasse

Patent number: 8303330Abstract: A continuous flexible bus comprises, for example, a plurality of metal clad flexible conductors. A device, such as a switch for example, is connected to the continuous flexible bus. In order to connect the device to the continuous flexible bus, at least one piercing connector is used, for example. The at least one piercing connector is configured, for example, to pierce one of the plurality of flexible metal clad conductors. Once the one of the plurality of flexible metal clad conductors is pierced, the at least one piercing connector causes, for example, an electrical connection between an electrical conductor in the pierced one of the plurality of flexible metal clad conductors and the switch.Type: GrantFiled: September 27, 2011Date of Patent: November 6, 2012Assignee: Southwire CompanyInventors: Richard Temblador, John R.
