Description
Bei biegsamen Leitungen mit Schutzerdungsgeflecht treten an den Kreuzungspunkten des Geflechtes, das gewöhnlich aus verzinnten Kupferdrähten gebildet wird, durch Druck oder Reibung der Drähte gegeneinander Beschädigungen auf, die bei auftretenden Erdschlüssen zu Zerstörungen des Schutzerdungsgeflechtes und damit zu einer Gefährdung des Bedienungspersonals führen können.In the case of flexible cables with protective earthing braiding, the braid usually comes out at the intersection points tinned copper wire is formed by pressing or rubbing the wires against each other Damage that, if earth faults occur, destroys the protective earthing braid and thus leads to a Endanger the operating personnel.
Gemäß der vorliegenden Erfindung wird diesem Übelstande dadurch begegnet, daß Kreuzungspunkte von Drähten, die den Strom zur Erde ableiten sollen, vermieden werden, indem das Geflecht in der Weise hergestellt wird, daß die in einem Windungssinne- verlaufenden Teile des Geflechtes nur aus Drähten oder Bändern aus leitendem Material und die im entgegengesetzten Sinne verlaufenden Teile des Geflechtes nur aus Fäden oder Bändem aus nichtleitenden Stoffen hergestellt sind.According to the present invention, this drawback is countered in that Crossing points of wires, which are supposed to divert the current to earth, are avoided, in that the braid is produced in such a way that the Parts of the braid consist only of wires or tapes made of conductive material and the parts of the mesh that run in the opposite direction are made up of threads or ribbons only are made of non-conductive materials.
In der Zeichnung stellt a die leitenden Teile, b die nichtleitenden Teile und c die Kreuzungspunkte des Geflechtes dar.In the drawing, a represents the conductive parts, b the non-conductive parts and c the intersection points of the mesh.
