摘要： A busbar for use in mechanically and electrically connecting components in a device or system. The busbar includes a plurality of conductors arranged to provide two opposed end portions and an intermediate portion, wherein each of the conductors has a plurality of intermediate extents that traverse the intermediate portion. The intermediate portion including: (A) an unfused segment where no intermediate extents of the conductors are fused together to form a single consolidated conductor, and (B) a fused segment that includes (i) a partial solidification zone where a majority of the intermediate extents of the conductors are fused together to form a partially solidified region that provides a single consolidated conductor, (ii) a full solidification zone where all of intermediate extents of the conductors are fused together to form a fully solidified region that provides a single consolidated conductor, and (iii) an unsolidified region where all of the intermediate extents of the conductors are not fused together.

摘要： A new dielectric material for a communication cable has a dielectric base with strength members embedded therein. By a new process, vacuum voids are formed in the dielectric base and at least partially contain or abut the strength members. The material is particularly well suited for a first dielectric tape, where the cable includes a first insulated conductor, the first dielectric tape and a second insulated conductor, with the first insulated conductor being twisted with the second insulated conductor with the first dielectric tape residing between the first insulated conductor and the second insulated conductor. The material is also suitable for a separator of the cable serving to separate twisted pairs from each other within the cable, as well as other components of the cable, such as an insulation layer of one or more of the insulated conductors of the twisted pairs.

摘要： A shielded electrical ribbon cable includes adjacent first and second longitudinal conductor sets where each conductor set includes two or more insulated conductors. The first conductor set also includes a ground conductor that generally lies in the plane of the insulated conductors of the first conductor set. At least 90% of the periphery of each conductor set is encompassed by a shielding film. First and second non-conductive polymeric films are disposed on opposite sides of the cable and form cover portions substantially surrounding each conductor set, and pinched portions on each side of each conductor set. When the cable is laid flat, the distance between the center of the ground conductor of the first conductor set and the center of the nearest insulated conductor of the second conductor set is σ1, the center-to-center spacing of the insulated conductors of the second conductor set is σ2, and σ1/σ2 is greater than 0.7.

摘要： Disclosed are cable types, including a type THHN cable, the cable types 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 material containing nylon or thermosetting resin. A silicone based pulling lubricant for said cable, or alternatively, erucamide or stearyl erucamide for small cable gauge wire, is incorporated, by alternate methods, with the resin material from which the outer sheath is extruded, and is effective to reduce the required pulling force between the formed cable and a conduit during installation.
