Description

Spannfeldmuffe zur Verbindung von Abschnitten bewehrter Luftkabel Die Erfindung befasst sich mit einer Spannfeldmuffe, die zur Verbindung von bewehrten Luftkabelabschnitten verwendet wird.Clamping field sleeve for connecting sections of armored aerial cables The invention relates to a clamping field sleeve, which is used to connect reinforced Air cable sections is used.

Solche Spannfeldmuffen werden zum Beispiel bei Nachrichtenkabeln eingesetzt, die zwischen den Masten einer Hochspannungsleitung aufgehängt werden. Dort dient die Bewehrung des Kabels manchmal sogar als Erdseil. Die Abstände solcher Masten, die üblicherweise bei etwa 400 bis 500 m liegen, verbieten in den meisten Fällen dasAnbringen von Verbindungsmuffen direkt an den Masten, da die Kabelabschnitte zwischen diesen enden.Such tension field sleeves are used, for example, in communication cables, which are hung between the masts of a high-voltage line. Serves there the armouring of the cable sometimes even as an earth wire. The distances between such masts which are usually around 400 to 500 m, prohibit in most cases attaching joint sleeves directly to the mast, as the cable sections between these ends.

Bei dieser Art von Kabelverbindungen sind im wesentlichen vier Probleme zu lösen. Erstens muss die Spannungsfestigkeit sehr hohe Werte haben, zweitens müssen die Bewehrungen der Kabelabschnitte elektrisch sehr gut miteinander verbunden sein, drittens muss die Zugfestigkeit hauptsächlich wegen des Kabelgewichtes und des Windes sehr hoch sein und viertens soll die Verbindungsstelle wasserdampfdicht sein.There are essentially four in this type of cable connection Problems to solve. First, the dielectric strength must have very high values, and second, must the armouring of the cable sections is very well connected electrically, Third, the tensile strength must be mainly due to the weight of the cable and the wind be very high and fourthly, the connection point should be water-vapor-tight.

Eine Ausführungsform einer solchen Spannfeldmuffe wird beschrieben in dem DT-GM 7 140 055. Dort werden Druckringe über die Kabelenden geschoben, die Drahtenden der Bewehrung umgebogen und die beiden Kabelenden mit den Druckringen unter Zwischenlegen eines Zwischenringes durch Zusammenschrauben einer zweiteiligen Hülse zusammengedrückt.An embodiment of such a clamping field sleeve is described in the DT-GM 7 140 055. There pressure rings are pushed over the cable ends that The wire ends of the reinforcement are bent over and the two cable ends with the pressure rings with the interposition of an intermediate ring by screwing together a two-part Sleeve compressed.

Die erfindungsgemässe Ausführung einer Spannfeldmuffe ist demgegenüber ohne kompliziert ausgebildete Armaturen schneller und einfacher herzustellen und ist so aufgebaut, dass die gespleissten Kabelleiterverbindungen gegeneinander und gegen die Bewehrung elektrisch isoliert und mit einem Schrumpfschlauch geschützt sind, dessen Durchmesser im geschrumpften Zustand geringfügig kleiner ist als der Durchmesser des bewehrten Kabels und über diese Kabelverbindungsstelle und Teile der blanken Bewehrung beider verbundener Kabelabschnitte innen metallisch angerauhte Spiralarmaturen aus Stahl gewickelt sind.In contrast, the embodiment of a clamping field sleeve according to the invention faster and easier to manufacture and without complicated fittings is constructed in such a way that the spliced cable conductor connections are against each other and electrically insulated from the reinforcement and protected with a shrink tube are whose diameter in the shrunk state is slightly smaller than that Diameter of the armored cable and over this cable joint and parts the bare armouring of both connected cable sections roughened metallic on the inside Spiral fittings are wound from steel.

Diese Spiralarmaturen können spiralig aufgewickelte flache Bänder oder aus mehreren nebeneinander liegenden miteinander verbundenen Runddrähten hergestellt sein. Spiralarmaturen der zuletzt genannten Art sind bekannt als Reparaturspiralen aus der Hochspannungstechnik.These spiral fittings can be spirally wound flat ribbons or made from several adjacent, interconnected round wires be. Spiral fittings of the last-mentioned type are known as repair spirals from high voltage technology.

Eine ausgeführte Spannfeldmuffe wird in der Figur gezeigt.An implemented clamping field sleeve is shown in the figure.

Hierin sind 1 die Spleisse zur Verbindung der Adern des Fernmeldekabels, 2 die elektrische Isolierung z.B. durch Bewickeln mit Isolierband, 3 der Kabelmantel, 4 der aufgeschrumpfte Schlauch, 5 die Bewehrung des Kabels und 6 aufgewickelte Reparaturspiralen.Here 1 are the splices for connecting the wires of the telecommunication cable, 2 the electrical insulation e.g. by wrapping with insulating tape, 3 the cable sheath, 4 the shrunk-on hose, 5 the armouring of the cable and 6 wound repair spirals.

In einer solchen Spannfeldmuffe wurden die Adern mit sogenannten Schleuderspleissen verbunden, diese Verbindung mit Glasgewebeband isoliert, mit einem Schrumpfschlauch überzogen, der die Verbindungsstelle zusätzlich wasserdampfdicht macht und diese Verbindungsstelle und die an beiden Seiten stehende Kabelbewehrung mit einer aus drei Teilen bestehenden 2,5 m langen Reparaturspiralen umwickelt. Durch die innen aufgebrachte metallische Rauhung ist eine gute elektrische Verbindung gewährleistet.In such a tension field sleeve, the cores were spliced with so-called centrifugal splices connected, this connection isolated with glass fabric tape, with a shrink tube coated, which also makes the connection point water-vapor-tight and this Connection point and the cable armor standing on both sides with one wrapped around three parts of existing 2.5 m long repair spirals. Through the inside applied metallic roughening ensures a good electrical connection.

Diese Verbindung wurde bis zu 6 t belastet. Dabei dehnte sich die Muffe um 20 mm, die Verbindung der Adern blieb intakt. Bei der oben angegebenen Belastung riss die Bewehrung des verwendeten Kabels ausserhalb der Spannfeldmuffe.This connection was loaded up to 6 t. The stretched Sleeve by 20 mm, the connection of the wires remained intact. at the one above specified load, the armouring of the cable used tore outside the clamping field sleeve.
