Abstract
PURPOSE:To attain a large transmission capacity without impairing either the tensile strength or the flexibility of the coh-ductor itself, by composing the insulated trolley sheathed in a continuous insulator having U-type cross secion with a high tension core material at the center and high conductive stranded wires stranded around the core. CONSTITUTION:The formed conductor 1 is manufactured by first preparing a high tension core 3 by stranding galvanized wires 2, and then placing on around this core, a stranded conductor 5 of stranded copper wires 4 having a size appropriate for the rated current capacity. The conductor 5 is then rolled from outside and reduced to an appropriate size with smooth surface 5a and V-shaped lays formed side by side. The molded insulator 6 is formed by introducing the formed conductor 1 into a plastic extruder whereby a U-formed insulator sheath is provide. As a result of this sheath forming operation by the extruder, separately standing fins 7 composing an opening 8 are provided at one side, and concaves 9 at both sides of oposite face. More than half of the smooth surfaces 5a and lays 5b of the conductor 1 is buried within the opening 8 with remainders set as the exposed portion.
