Description
Hohlseil mit um eine Einlage verseilten Drähten, insbesondere für elektrische Freileitungen Für den Aufbau von Hohlseilen, wie sie insbesondere für elektrische Freileitungen bei hohen Spannungen in Betracht kommen, ist bereits vorgeschlagen worden, die Drähte um eine schlauchartige Einlage zu verseilen. Als Einlage ist dabei gewöhnlich eine Drahtschraube vorgesehen worden. Erfindungsgemäß. soll statt dessen ein gitterartiger Hohlkörper benutzt werden,. der aus sogenanntem Streckmetall hergestellt ist. Die Verwendung eines derartigen Körpers als Einlage hat gegenüber der Verwendung der Drahtschraube den Vorteil, daß man bei gleichem Aufwand an Werkstoff eine größere Festigkeit erhält. überdies ergibt sich dabei eine günstigere Ausbildung der Auflagefläche für die verseilten Drähte. Die Einlage nähert sich in dieser Beziehung einem geschlossenen Rohrkörper, erfordert aber wesentlich weniger Werkstoff und hat infolgedessen ein geringeres Gewicht, während zugleich die Biegsamkeit in erwünschter Weise besser ist.Hollow rope with wires twisted around a core, especially for Electric overhead lines For the construction of hollow ropes, such as those used in particular for Electric overhead lines come into consideration at high voltages, has already been proposed to strand the wires around a tube-like insert. As a deposit is a wire screw has usually been provided. According to the invention. should take place of which a lattice-like hollow body can be used. the one made of so-called expanded metal is made. The use of such a body as an insert has opposite the use of the wire screw has the advantage that you can use the same amount of material receives greater strength. In addition, this results in a cheaper training the support surface for the stranded wires. The deposit approaches in this regard a closed tubular body, but requires significantly less material and As a result, it has a lower weight, while at the same time the flexibility is more desirable Way is better.
Zur Herstellung der Einlage kann man einfach derart verfahren, daß ein Rohr in der Achsrichtung oder auch in der Umfangsrichtung mit parallelen abwechselnd gegeneinander versetzten Reihen von Schlitzen versehen und dann senkrecht zu diesen Schlitzen einer Zugbeanspruchung ausgesetzt wird, bis sich durch Aufweiten der Schlitze die Gitterform ergibt.To produce the insert one can simply proceed in such a way that alternating a tube in the axial direction or in the circumferential direction with parallel staggered rows of slots provided and then perpendicular to these Slitting is subjected to tensile stress until the slits are widened the lattice shape results.
In der Zeichnung ist ein Ausführungsbeispiel für ein solches Hohlseil dargestellt. Das Seil besteht dabei aus zwei Drahtlagen a, ä, die mit entgegengesetztem Drall aufgewickelt sind. c ist der als Einlage dienende gitterartige Hohlkörper aus Streckmetall. Dieser Hohlkörper kann aus dem gleichen Werkstoff bestehen wie- die aufgewickelten Drähte. Gegebenenfalls läßt er sich aber auch aus einem geeigneten anderen Werkstoff ausführen.The drawing shows an exemplary embodiment for such a hollow rope shown. The rope consists of two layers of wire a, ä, which are opposite Twist are wound. c is the lattice-like hollow body serving as an insert made of expanded metal. This hollow body can consist of the same material as the coiled wires. If necessary, however, it can also be derived from a suitable one other material.
