摘要： The present invention provides a movable cable, which has strength that is at least equal to conventional movable cables while having excellent flexural fatigue resistance and flexibility as well as being lightweight. This movable cable 10 has an electric conductor therein. The conductor comprises a first conductor 2 made of a specific aluminum alloy material wherein: the alloy composition contains, in mass %, 0.05-1.8% Mg, 0.01-2.0% Si, 0.01-1.5% Fe, and at least a total of 0.00-2.00° of one element selected from the group consisting of Cu, Ag, Zn, Ni, Co, Au, Mn, Cr, V, Zr, Ti and Sn, the balance being Al and unavoidable impurities; the crystal grains have a fiber-like metal structure in which the crystal grains all extend in one direction; and in a cross-section parallel to the one direction, the average crystal grain dimension perpendicular to the longitudinal direction is 400 nm or less. The ratio X of the area of the first conductor 2 in the whole conductor of the movable cable 10 is in the range of 10-100%.

摘要： The present invention relates to electrical conductors for electrical transmission and distribution with pre-stress conditioning of the strength member so that the conductive materials of aluminum, aluminum alloys, copper, copper alloys, or copper micro-alloys are mostly tension free or under compressive stress in the conductor, while the strength member is under tensile stress prior to conductor stringing, resulting in a lower thermal knee point in the conductor.

摘要： A helical jumper connector includes a helical support member configured to support a wire. The helical support member includes a first leg having a first helical winding and a second leg having a second helical winding that defines a second axial opening. The first axial opening and the second axial opening are coaxial with the wire when the first helical winding and the second helical winding are wrapped around the wire and cooperatively engage with one another to support the wire. A jumper casting is configured to receive the helical support member. The helical support member and the jumper casting are electrically conductive such that the helical jumper connector forms an electrically conductive pathway to carry electrical current from the wire. A method of making a helical jumper connector assembly includes applying a compression force to a helical jumper connector comprising a helical support member received in a jumper casting.
