Description
Zuweilen besteht das Bedürfnis, den Bleimantel eines Kabels gegen Erde zu isolieren. Als Werkstoffe für diese isolierende Bekleidung sind beispielsweise Guttapercha, Biturnen, Gummi und Gutta-Gentzsch vorgeschlagen worden. Bei der Vierwendung von Gummi ergibt sich die Notwendigkeit, diesen nach dem Aufbringen auf dem Bleimantel warm zu vulkanisieren. Es .wäre nun 'ein ίο äußerst zeitraubendes und kostspieliges Verfahren, wenn man den infolge des Aufbringungsverfahrens heißen Bleimantel des Kabels erst abkühlen lassen, dann mit der Gummimischung umkleiden und hierauf unter nochmaligeir Erwärmung 'die Gummimisichüng vulkanisieren wollte. Zudem könnte bei dem Kabel die Leiterisolierung durch die nochmalige Erwärmung geschädigt werden.Sometimes there is a need to isolate the lead sheath of a cable from earth. The materials for this insulating clothing include, for example, gutta-percha, biturns, Gummi and Gutta-Gentzsch have been proposed. When turning rubber there is a need to use this to vulcanize warm after application on the lead jacket. It 'would now' be a ίο extremely time-consuming and costly process, when the lead sheath of the cable, which is hot as a result of the application process Let it cool down first, then cover it with the rubber mixture and then add the rubber mixture while heating it again wanted to vulcanize. In addition, the wire insulation of the cable could be caused by the repeated Warming.
Gegenstand der Erfindung ist ein Verfahren, bei dem das Aufbringen des vulkanisierbaren
Isolierstoffs auf den Bleimantel des Kabels in dem gleichen Arbeitsgang wie das
Umpressen der Kabelseele mit dem Bleimantel .erfolgt. Die Tempieratur und der
Wärmegehalt des eben erstarrten Bleies reichen aus, um in einer Zeit von beispielsweise
V2 bis ι Minute den Vulkanisationsvorgang
zu vollziehen, wenn an sich bekannte VuI-kanisationsbeschleuniger
zu Hilfe genommen werden. Das Herstellungsverfahren des Kabels wird durch Anwendung der Erfindung
wesentlich abgekürzt und verbilligt und eine Beschädigung der Leiterisolierung durch nochmaliges
Erwärmen vermieden.
3S Das Aufbringen des Gummis kann nach
einem der bekannten Verfahren erfolgen. In Abb. ι ist das »Aufscheren« des Gummis dargestellt.
Auf das aus der Bleipuesse P (von oben gesehen) kommende Kabelt werden
durch Profilwalzen B1 und B2 die von
den Vorratstrommeln A1 und A2 abgezogenen
Gummistreifen G1 und G2 aufgepreßt. In der
Naht N kleben die erwärmten Gummibänder fest und zuverlässig zusammen.The invention relates to a method in which the vulcanizable insulating material is applied to the lead sheath of the cable in the same operation as the lead sheath is pressed around the cable core. The temperature and the heat content of the lead that has just solidified are sufficient to complete the vulcanization process in a time of, for example, V 2 to ι minute, if VuI-Kanization accelerators known per se are used. The manufacturing process of the cable is significantly shortened and cheaper by using the invention and damage to the conductor insulation by repeated heating is avoided.
3 S The rubber can be applied using one of the known methods. In Fig. Ι the "shearing open" of the rubber is shown. On the (viewed from above) from the Bleipuesse P coming cables are by roll forming B 1 and B 2 of the storage drums A 1 and A 2 are withdrawn rubber strip G 1 and G 2 are pressed. In the seam N, the heated rubber bands stick together firmly and reliably.
In Abb. 2 ist die Aufbringung des Gummis in 'schraubenförmigen Bändern dargestellt. Auf das aus der Bleipresse/> (hier von der Seite gesehen) kommende Kabel/C wird der Gummistreifen G aufgebracht, der von der Trommel Γ abläuft, die als Teil der Bewicklungsmaachine B um die Kabelachse herumläuft. Das Gummiband klebt hier in der Naht N ebenfalls fest zusammen.Fig. 2 shows the application of the rubber in helical bands. The rubber strip G is applied to the cable / C coming from the lead press /> (here seen from the side), which runs off the drum Γ, which runs around the cable axis as part of the winding machine B. The elastic band also sticks firmly together in the seam N.
In beiden Fällen ist der Vulkanisationsprozeß bis zum Auflaufen des Kabels auf den Haspel bereits im wesentlichen beendet.In both cases, the vulcanization process continues until the cable runs onto the The reel has essentially ended.
Um zu vermeiden, daß beim Stillsetzen der Bleipuesse ein übermäßiges Erkalten eines Teils des Bleimantels und damit eine mangelhafte Vulkanisation eines Teils des Gummi-Überzuges .eintritt, erfolgt die Aufbringung des Gummis auf den Bleimantel sehr nahe an der Presse. Dann genügt die Wärmeleitfähigkeit des Bleimantels, um das zwischen der Auistrittssteüe aus der Presse und der Aufwickelstelle des Gummis liegende Stück des Bleimantels auf genügend hoher Temperatur zu halten.In order to avoid excessive cooling of a Part of the lead jacket and thus poor vulcanization of part of the rubber coating . occurs, the application of the rubber to the lead jacket takes place very close to the press. Then the thermal conductivity of the lead jacket is sufficient to ensure that between the Auistrittssteüe from the press and the The piece of lead jacket lying at the point where the rubber is wound up at a sufficiently high temperature to keep.
