Description

Die Erfindung betrifft die Isolation von elektrischen Kabeln für Starkstrom, bei denen die einzelnen Adern in Sektorform ausgebildet sind. Die übliche Form der Isolierung der einzelnen Adern ist das Umspinnen der Adern mit Papierbändern. Es ist bekannt, daß die Papierbespinnung der Adern leicht zerdrückt wird, wenn die einzelnen Adern in Sektorform miteinander verseht werden. Diese Gefahr ist insbesondere dann groß, wenn die Verseilung ohne Rückdrehung der Adern, d. h. mit nicht vorgeformten Adern erfolgt. Um diese Nachteile zu beheben, sind bereits Vorschläge bekanntgeworden, die sämtlich auf eine besondere Art der Bespinnung der Adern hinauslaufen; jedoch ist mit den bekannten Verfahren ein Zerquetschen der Papierisolation nicht mit Sicherheit zu vermeiden.The invention relates to the insulation of electrical cables for heavy current, in which the individual wires are designed in a sector shape. The usual form of the Isolation of the individual cores is the wrapping of the cores with paper tapes. It it is known that the paper spinning of the veins is easily crushed when the individual cores are provided with each other in sector form. This danger is particular then great if the stranding without reverse rotation of the cores, d. H. with not preformed Veins takes place. In order to remedy these disadvantages, proposals have already become known, all of which result in a special kind of spinning of the veins; However With the known methods, crushing of the paper insulation is not certain to avoid.

Um auch beim Verseilen von Adern in Sektorform eine Beschädigung der Papierisolation mit Sicherheit auszuschließen, werden erfindungsgemäß als Isolation parallel zu denAdern laufende Bänder aus Isoliermaterial, insbesondere Papier, verwendet. Vorteilhaft werden hierbei mehrere einander überlappende Papierbänder mit am Umfang der Adern versetzten Überlappungsstellen verwendet. Das Aufbringen der Bänder erfolgt auf der Kabelverseilmaschine kurz vor dem Zusammenlaufen der Adern zum Kabel.In order to avoid damage to the To exclude paper insulation with certainty, according to the invention as insulation strips of insulating material, in particular paper, running parallel to the veins are used. A plurality of overlapping paper tapes on the circumference are advantageous here of the cores staggered overlap points are used. The tapes are applied on the cable stranding machine shortly before the wires converge to form the cable.

Ein Ausführungsbeispiel der Erfindung ist im folgenden an Hand der Zeichnung beschrieben (Fig. z und 2). Diese zeigt einen Drehstromsektorkabel. Die einzelnen Adern sind mit i bezeichnet. Jede Ader ist von einer dreilagigen Papierisolation umgeben. Die einzelnen Lagen sind mit 2, 3 und q. bezeichnet; sie sind gegeneinander versetzt auf die Adern aufgebracht, so daß auch die Überlappungsstellen am Umfang der Adern versetzt sind.An embodiment of the invention is shown below with reference to the Drawing described (Fig. Z and 2). This shows a three-phase sector cable. the individual wires are marked with i. Each wire has a three-layer paper insulation surround. The individual layers are marked with 2, 3 and q. designated; they are against each other applied offset to the veins, so that the overlap points on the circumference the veins are staggered.

Die Kabelseele ist von einer Isolation 5 bekannter Art umgeben, die wiederum vom Kabelmantel 6 umschlossen ist.The cable core is surrounded by an insulation 5 of a known type, the is in turn enclosed by the cable jacket 6.
