Description

Blei den bekannten, selbsttrggexvden Fernmeldeluftkab:ein ist zwischen dem Bleimantel und der zugfesten Bewehrung eine Polsterschicht angeordnet, dile den Bleimantel bei der Herstellung und im Betriebe des Kabels gegen. mechanische: Beschädigung,durch ,die Beweh=g ;s:chützt. Da, idiesie Polsterschicht gleichzeitig elektrisch isoliert; treten bei Blitzsidhlägen in das Luftkabel :oder in seiner Nähe zwischen Bleimantel :und Bewehrung S,pamungsunterschiede auf, die reine solche Höhe ierreichen können, daß .die P:olsters,cbidht -durchschlagen und der Bleimantel auf größere Strecken beschädigt oder zerstört wird. Um dies -zu vermeiden, ist schon vorgesidhlagen worden, den Bleimantel und die Bewehrung,desLuftkabels inAb@ständen ;oder -stetig,durch leitende Einlagen elektrisch leitend zu verbinden,. Hierzu hat man z.

To avoid this is nice the lead jacket and the armouring of the air cable at intervals ; or -continuous, to be connected in an electrically conductive manner by means of conductive inserts.

Erfindungsgemäß besteht,die zugfeste Bewehrung des, selbsttragenden Fernmeldeluftkabels ;aus einer unmittelbar auf den Metallmantel des Kabels aufgebrachten verschlossenen Verseillage aus Formdrähten; die nach Axt von Feder und Nut verklinkt sind und sein Rohr von glatter Innenfläche um Aden Kab:ehnantel bilden. Dadurch, idaß die Formdrähte dweser Bewehrung sich: infolge ihrer Verklinkung nicht iaius ihrer Vers,eialaige verschieben können, bleibt die Innenfläche der Bewehrung stets glatt, und die bisher iunu;mgängliche Polsterung des Kabzlinantels ist entbehrlich. Gleichzeitig ist nach der Erfindung idurch die unmittelbare Berührung zwischen MetadImantel- und -Bewehrung -eine unter allen Umständen zuverlässige elektrisch leitende Verbindung zwischen -diesen Bauteiaen des Kabels gewährleistet. Das selbsttragende FernmeIdeluftkab,el nach der Erfindung eignet sich daher insbiesiondere zur gleichzeitigen Verwendung als Blitzschutzsei.l in Hochspannungsfreileitungsanlagen.According to the invention, the tensile reinforcement of the self-supporting Telecommunication air cable; from one applied directly to the metal jacket of the cable closed stranded layer of shaped wires; which is latched according to the ax of tongue and groove and form its tube of smooth inner surface around Aden Kab: ehnantel. Through this, that the shaped wires are reinforced: not iaius due to their latching their verse, egg-lined can move, the inner surface of the reinforcement always remains smooth, and the previously common padding of the Kabzlin jacket is dispensable. At the same time, according to the invention, the direct contact between the meta-shell- and reinforcement - an electrically conductive connection that is reliable under all circumstances guaranteed between these components of the cable. The self-supporting FernmeIdeluftkab, el according to the invention, therefore, it is particularly suitable for simultaneous use as lightning protection in high-voltage overhead line systems.

Die Zeichntung zeigt beis,püelsweise eine Ausführungsform des selbsttragenden F'ernmeldeluftkabeJs nach der Erfindung. Es hezeithnen r die Sieele und a den Bleimantel -des Kabels. Darüber ist unmittelbar und mit langem Schlage die verschlossiene Lage 3 der Bewehrung verseht, deren Z-Drähte wie Feder und Nut ineinaindergreifen.The drawing shows an embodiment of the self-supporting püelsweise Telecommunication air cables according to the invention. There are now the seals and the lead sheath -of the cable. Above it is the locked position immediately and with a long stroke 3 of the reinforcement, the Z-wires of which interlock like tongue and groove.

Über der verschlossenen Verseillage 3 der Bewehrung kann zum Ausgleich des Drehmomentes unter der Zugbelastung eine weitere, im @entgegengesetzten Sinn gescMagene Verseillage aufgebracht siexn, die nicht verschlössen zu sein braucht.Over the closed stranding layer 3 of the reinforcement can compensate of the torque under the tensile load another, in the opposite sense A smoked stranded layer is applied, which does not need to be closed.
