Description
Verseilter Hochspannungsleiter Es ist ein verseilter Hochspannungsleiter bekannt, bei dem .die Einzelleiter einen geschlossenen Leitermantel aus Teilleitern von im wesentlichen ringstückähnlichem Querschnitt bilden. Der Leitermantel ist um eine Seele großen Durchmessers angeordnet, die als Tragorgan dient. Bei einer Ausführungsform wird als Tragorgan eine isolierende Seele verwendet, in die eine oder mehrere Tragdrähte eingebettet sein können.Stranded high voltage conductor It is a stranded high voltage conductor known, in which .die single conductor a closed conductor sheath made of partial conductors form of a substantially ring piece-like cross-section. The ladder jacket is arranged around a soul of large diameter, which serves as a support member. At a Embodiment is used as a supporting member, an isolating soul in the one or several supporting wires can be embedded.
Die Erfindung betrifft ebenfalls einen verseilten Hochspannungsleiter, bestehend aus Ringstück-]eitern, die unter Zwischenlage eines Beilaufs aus Jute oder Hanf über eine Stahlseele gewickelt sind. Erfindungsgemäß ist die Schlaglänge der äußeren Schicht so gewählt, daß sie bei zusätzlicher Beanspruchung unter gleichzeitiger Veränderung des Leiterdurchmessers nachgeben kann. Zweckmäßig wird die Decklage aus ringstückä`hnlichen Leitern mit so kurzer Schlagweite aufgebracht, daß bei Kontraktion des Seils infolge Abkühlung für die Decklage eine Art Federwirkung zustande kommt, so daß die entstehende höhere mechanische Zugspannung überwiegend vom Stahlkern: aufgenommen wind, während sich die Aluminiumdecklage nur in verhältnismäßig geringem Ausmaße idiaran beteiligt.The invention also relates to a stranded high-voltage conductor, consisting of ring pieces] festering with a jute fillet in between or hemp are wrapped around a steel core. The lay length is according to the invention the outer layer is chosen so that it is subject to additional stress at the same time Change in the conductor diameter can give way. The top layer is useful made of ring piece-like ladders with such a short throw that when contraction occurs the rope has a kind of spring effect for the top layer as a result of cooling, so that the resulting higher mechanical tensile stress mainly comes from the steel core: recorded wind, while the aluminum top layer is only relatively low Extents idiaran involved.
Ein Hochspannungsleiter gemäß der Erfindung besteht also wiederum aus einer Stahlseele, über die ein Beilauf aus Jute, Hanf od. dgl. gewickelt ist. Darüber liegen dann die eigentlichen Leiterteile, die ringstückähnliche Form haben und bei normaler Zugspannung und Temperatur praktisch fugenlos aneinanderliegen. Diese in der Hauptsache aus Aluminium bestehenden Teilledter sind aber mit so kurzer Schlaglänge aufgebracht, d.aß bei einer Kontraktion des Seils bei niedrigen Temperaturen eine Federwirkung zustande kommt. Die Teilleiter verändern daher -bei einer Änderung der Leiterlänge ihren Durchmesser, und zwar in der Weise, daß sie sich .entweder spreizen und einen größeren Durchmesser annehmen oder zusammenziehen, wobei die dann eintretende Durchschnittsverminderung von.. dem elastischen Material des Beilaufs aufgenommen werden muß. .Diese elastische Zwischenschicht sorgt also, dafür; daß bei Zunahme .d!er Seilspannung -die äußere Decklage von mechanischen Zusatzbeanspruchungen freigehalten wird.A high-voltage conductor according to the invention thus exists again from a steel core, over which a filler made of jute, hemp or the like is wrapped. The actual conductor parts, which are shaped like a ring piece, then lie above this and at normal tensile stress and temperature, lie against one another practically seamlessly. These partial leather, which is mainly made of aluminum, are so short Lay length applied, i.e. a contraction of the rope at low temperatures a spring effect comes about. The sub-conductors therefore change when there is a change the diameter of the conductor length, namely in the way that they either spread and take on a larger diameter or contract, where the then occurring mean reduction of ... the elastic material of the Beilauf must be included. .This elastic intermediate layer ensures Therefore; that as the rope tension increases, the outer top layer of mechanical Additional stresses are kept free.
