Description

Verfahren zur Verstärkung von schwächeren Leitern oder Adern für gleichförmige oder symmetrische Anordnung oder Verseilung mit stärkeren Leitern zu Mehrfachleitungen. Bekanntlich lassen sich Leiter verschiedener Stärke zu Mehrleiterkabeln in einer oder mehreren Lagen zu einem regelmäßigen Gebilde mit möglichst vollkommener Raumausnutzung, also ohne unzulässig große tote Räume, -in vielen Fällen überhaupt nicht oder nur in der Weise verseilen, daß die schwächeren in die Lücken -zwischen den stärkeren Adern gelegt werden, wenn die Zahl und Stärke der verschieden starken Leiter oder Adern hierfür paßt. Dieses ist häufig nicht der Fall. Um nun zu einer regelmäßigen - für eine gute Verseilung vorzugsweise möglichst runden Anordnung der Leiter -zu kommen, ist man oft gezwungen, die Durchmesser einzelner oder aller dünneren Leiter durch vorzugsweise entsprechende Verstärkung ihrer Isolation mit dem Außendurchmesser der isolierten stärkeren gleich zu machen; denn die Verstärkung des Durchmessers durch Isolierstoffe o. dgl. ist meistens billiger als die Verstärkung des metallischen Leiters selbst.Method of reinforcing weaker conductors or veins for uniform or symmetrical arrangement or stranding with thicker conductors to form multiple cables. As is well known, conductors of different strengths can be converted into multi-conductor cables in one or several layers to form a regular structure with the best possible use of space, that is, without impermissibly large dead spaces - in many cases not at all or only at all Strand in such a way that the weaker ones get into the gaps between the stronger ones Veins are laid when the number and strength of the conductor or of different strengths Cores for this fits. This is often not the case. To now become a regular - For a good stranding, preferably the most round arrangement of the conductors -zu come, one is often forced to determine the diameter of individual or all thinner conductors by preferably corresponding reinforcement of their insulation with the outer diameter to make equal to the isolated stronger; because the gain in diameter by insulating materials or the like. Is usually cheaper than reinforcing the metallic Leader himself.

Gemäß der Erfindung wird nun die Verstärkung der Isolation dünnerer Leiter, wenn es ihre Betriebsspannung und -weise zuläßt, ihre elektrische Festigkeit also die Verstärkung nicht erfordert, um Arbeit und Isolationsstoff zu sparen, in der Weise vorgenommen, daß nicht der ganze für dieVerstärkung in Frage kommende Raum um den Leiter mit geeigneten Stoffen vollständig angefüllt, sondern hohl gemacht wird. Beispielsweise wird dieses nach der Erfindung dadurch erreicht, daß die- Isolation um die dünneren Leiter in den an sich bekannten Ausführungsarten der Hohladern von Papierluftraum-Fernsprechkabeln als Ballon- oder Spagatader oder als genügend festes aber hinreichend. biegsames, hohl um den Leiter liegendes Rohr aus mehreren Lagen Papier ausgeführt wird. Der Leiter selbst kann blank oder isoliert sein, z. B. eine Isolation von festaufliegendem Papier oder Emaillelack usw. besitzen, über welche dann die hohle Isolation aufgebracht ist. Über den dünneren, isolierten Leiter ist z. B. eine offene Spirale aus Papierkordel und darüber eine zweite geschlossene Papierumspinnung gelegt, oder eine entsprechend weite Papierumspinnung wird durch Einschnürungen mittels eines Fadens wie bei der Ballonader auf dem blanken oder isolierten Leiter zentrisch gehalten: Die notwendige Verstärkung des Leiters, z. B. für die runde Verseilung eines Vierleiterkabels mit drei stärkeren und einem nur 1/2 bis 1,l2 so starken Leiter als Nulleiter eines Drehstromkabels, wird auf diese Weise möglich, ohne den vierten Leiter durch feste Umspinnung oder Umpressung mit Isolier- oder Füllstoff auf den Durchmesser der übrigen stärkeren Leiter zu bringen unter Ersparnis an Arbeit, Zeit und vor allen Dingen Stoff.According to the invention, the reinforcement of the insulation is now thinner Conductors, if their operating voltage and operating mode permit, their electrical strength so the reinforcement does not require in order to save labor and insulation material made in such a way that not all of them are eligible for reinforcement Space around the ladder is completely filled with suitable materials, but made hollow will. For example, this is achieved according to the invention in that the insulation around the thinner conductors in the known types of loose tubes from Paper airspace telephone cables as balloon or split arteries or as sufficiently solid but sufficient. flexible tube made of several layers and lying hollow around the ladder Paper is running. The conductor itself can be bare or insulated, e.g. Legs Have insulation from firmly attached paper or enamel paint, etc., over which then the hollow insulation is applied. About the thinner, insulated conductor is z. B. an open spiral made of paper cord and above a second closed Paper wrapping laid, or a correspondingly wide paper wrapping is through Constrictions by means of a thread as with the balloon vein on the bare or insulated conductor held centrally: The necessary reinforcement of the conductor, e.g. B. for the round stranding of a four-core cable with three stronger and one only 1/2 to 1, l2 as strong a conductor as the neutral conductor of a three-phase cable is on in this way possible without the fourth conductor by means of fixed wrapping or crimping with insulating or filler material towards the diameter of the other stronger conductors bring savings in work, time and, above all, material.
