Turning braid is made up of wires. In spite of the same flexibility and twistability, it is known that the wire used as shielding shows that such a braid has to be implemented as a braid when it is practically liüllen, be it only half the weight of a braiding of the cable core (German Auslegeschrifl 30 knitted cover due to the same direct conductivity) same material.

sufficiently flexible, but not sufficiently twisted. Below is an exemplary embodiment of the Urbars, explained in more detail with reference to the drawing, in that a stepped end of a line formed according to the invention by the use of wire sleeves is illustrated in significantly better rotatability is.
In the drawing, two leaf-forming processes, such as knitting or warp-knitting, are made up of wire groups each consisting of two wires (German patent 972 701). This is denoted by α and b. However, they are bought at the price of formation in each case with the disadvantage that, in order to achieve that of a web c, they are brought together and the same longitudinal conductivity in the case of knitted ribbons is then removed from one another in order to at the point.! greater distance a greater weight of copper is required than with the perforation with the adjacent one on the other side. The reason is that a knitted band 45 th wire group in turn to form a web c,
Only from a continuous wire or a wire group follows the conductor 1 as ionization protection, whereas a braided band consists of numerous conductive rubber layer 2, an insulation 3 and a small parallel-connected wires or wire group further conductive rubber layer 4. Above it pen exists. The portion of the wire contact points is a metallic shielding according to the invention with their transition resistances on the wire mesh 5, a further conductive rubber of the current is therefore essentially a mixed layer 6 and an outer jacket 7 in the first case.
higher than the second. Instead of the shielding shown in the drawing, the invention is based on the object of creating a wire sheathing that can also be used with a braided band with known shielding, th braiding machines a direct braiding which has the same good twistability as:; ine 55 cable core.
