Description
Verfahren zur Herstellung von Drei- und glehrleiter-Starkstromgummikabeln mit einer dicken zentrischen Traglitze Die Erfindung betrifft ein Verfahren zur Herstellung von Drei- oder Mehrleiber-Starkstremgummikabeln, die eine Stahllitze zur Erhöhung dir Zugfestigkeit des Kabels enthalten, welche so dick ist, daß die Adlern sich nicht gegenseitig berühren. Werden drei Reit Gummi isolierte Einzeladern um eine derartige Stahlseele verseht, und bringt man darüber die äußere Gummiisolation auf, so erhält man ein Gummikabel, welches den in Abb. z dargestellte: Querschnitt zeigt. Die drei Adern verteilen sich bei: einer normalen Verseilung nicht, wie @es erwünscht ist, gleichmäßig um die StahIlitze, sondern sie gleiten nach der Verseilung durch den Verseilzug bis zur Berührung zusammen. Geht man andererseits so vor, daß span die Sltahlätze gemeinsam mit dien g"m,m;;soliexten Einzeladem. verseift, so erhält man eine Litze, die den i- Abb. z dargestellten Querschnitt aufweist. In dir Falle legt die Stahllitze in Form der Trense in Kabel. und gibt bei der Beanspruchung des Kabels auf Zug zu Zerrungen, im Innern des Kabels Anlaß.Process for the production of three-wire and sliding ladder heavy current rubber cables with a thick central support strand The invention relates to a method for Manufacture of triple or multi-core heavy-duty rubber cables with a steel strand to increase the tensile strength of the cable, which is so thick that the Eagles do not touch each other. Will be three riding rubber insulated single cores around such a steel core, and one brings the outer rubber insulation over it on, you get a rubber cable which has the cross-section shown in Fig. z shows. The three cores are distributed with: a normal stranding not, like @es it is desirable to have them evenly around the steel strand, but they slide after the stranding by the stranding up to the point of contact. On the other hand, if one proceeds in such a way that span the sltahlätze together with dien g "m, m ;; soliexten single academy. saponified, so a strand is obtained which has the cross-section shown i- Fig. z. In dir trap puts the steel braid in the form of a bridle in a cable. and gives when it is used pulling the cable, causing strain inside the cable.
Um die Nachteile der vorerwähnten Verfahren zu vermeiden:, wird gemäß der Erfindung die -StaMseele zunächst Reit unvulkanisiertem Weichgummi umpneßt, und über die so vorbehandtelte Litze werden. die gummiisolierten Einzeladern. init gier normalen Schlaglänge (ro- bis izfaeh), verseift. Hierbei quetscht sich die auf der 'Stahllitze befindliche umvulkanisierte, also noch plastische Gummimasse ih. die Zwischenräume zwischen die Adern, so daß sie in gleichmäßigem Abstand voneinander zu liegen kommen. Nach der Verseilung ward der äußere gemeinsame Gummimantel aufgebracht und zusammen mit der Waicbgumniihülle der Traglitze vulkanisiert. Man ierhält auf diese Weise ein Kabel, das den. in Abb.3 gezeichneten Querschnitt zeigt. Das gleiche Verfahren wird mit Vorteil angewandt, wenn es sich um die Verseilung von vier oder mehr sich nicht berührenden isolierten Adern um eine dicke Stahllitze handelt. Es isst aber von besonderem Werte gerade bei Dreileher-Kabeln, weil. hier die Neigung zu eeiner, einseitigen Verlagerung der Adern bei Verwendung dicker Stahlseelen und normaler Verseilung besonders groß ist.In order to avoid the disadvantages of the aforementioned methods:, according to the invention, the -StaMseele first peezes around riding unvulcanized soft rubber, and over the pre-treated strand. the rubber-insulated single cores. init greed normal lay length (ro- to izfaeh), saponified. Here the squeezes on the 'steel strand located umvulcanized, so still plastic rubber compound ih. the spaces between the wires so that they are evenly spaced from each other come to rest. After the stranding, the outer common rubber jacket was applied and vulcanized together with the Waicbgumniihülle of the support strand. You stop this way a cable that has the. shows the cross-section drawn in Fig. The same This method is used to advantage when it comes to stranding four or four more insulated wires that are not touching are thick steel braids. It but eats of particular value, especially with three-wire cables, because. here the slope to a one-sided shift of the cores when using thick steel cores and normal stranding is particularly large.
