Patent 515,939 relates to a conduit connection for high-voltage overhead lines, in which the sub-conductors of the rope ends before the Introducing into the terminals are soldered together so that the individual sub-conductors one close connection between each other and it is not possible that the individual sub-conductors of the rope are isolated from each other by oxidation. Such a line connection is shown in Fig. 1. However, there is a risk that at high stress on the rope at points 3 and 4, 7 "and 8, the rope breaks because the structure of the rope also outside through the soldering process or welding the actual soldering points have changed significantly.

This risk of breakage is according to the invention

reduced by only the outermost ends of the The rope can be soldered or welded appropriately after it has been introduced into the terminals the ends of the rope protrude a little more than usual from the connecting clamp. The solder runs at the Solder in the grooves left behind when the rope was stranded up to the area the clamps and cools there. As a result, the sub-conductors of the rope, which are are inside the terminal, properly connected to each other. The metal mass of the Clamp itself serves as thermal protection for the rope and prevents the behind the Clamp after the line route to located part of the rope is changed by heating in its structure. So that adjacent rope is not heated during soldering or welding, a heat-insulating plate or the like is placed between the two ropes. In Fig. 1 a line connection according to patent 5 * 5 939 is shown in the drawing. In it mean 2 and 3, the ends of the overhead lines 4 and

5. The sub-conductors of the line ends are mechanically and electrically connected to one another by soldering or welding. 6 shows the connecting terminal. As a result of the soldering process is the structure of the 'wire ropes changed significantly. As the heating up to the points 7 and 8 has taken place, there is an increased risk of breakage at these points.

Fig. 2 shows a line connection according to the invention. In it are 22 and 23 the cables, which are connected to one another by a clamp 24. To prevent, that the onset of oxidation on the surfaces of the individual sub-conductors of the rope the sub-conductors isolated from each other, the outermost ends 25 and 26 of the rope are soldered or welded. The liquid one Solder runs in the grooves up under the terminals and makes "a safe electrical" and mechanical connection of the individual sub-conductors to one another.
