Description

Hochfrequenzkabel mit Luftraumi;olation Um 'Kabel mit schraubenlinienförmig gewickelten Metallbändern torsionsfrei zu machen, wird die über den Metallbändern liegende Bewehrung aus Metalldraht oder -band mit entgegengesetzter Schlagrichtung aufgebracht.High frequency cable with air space around 'cable with helical shape To make wrapped metal bands torsion-free, the over the metal bands Horizontal reinforcement made of metal wire or tape with opposite direction of lay upset.

Es hat sich nun gezeigt, daß bei Hochfrequenzkabeln mit konzentrischer Leiteranordnung und Luftr aumisolation, also mit nachgiebiger Isolation unter den Metallbändern, und der üblichen Bewehrung die Metallbänder bei Biegungs- oder Torsionsbeanspruchungen des Kabels leicht einknicken. -Zur Vermeidung solcher Einknickungen werden erfindungsgemäß die Bänder, die als Rückleitung dienen, in bekannter Weise in steilgängiger Schraubenlinie aufgewickelt und darüber die Draht- oder Bandbewehrung mit derselben Schlagrichtung wie die der Metallbänder aufgebracht. Es hat sich ergeben, daß die Bänder der so aufgebauten Kabel nicht mehr eingedrückt werden.It has now been shown that with high frequency cables with concentric Conductor arrangement and air space insulation, i.e. with flexible insulation under the Metal strips, and the usual reinforcement, the metal strips for bending or torsional loads bend the cable slightly. To avoid such kinks, according to the invention the bands, which serve as the return line, in a known manner in a steep helix wound up and above the wire or tape reinforcement with the same lay direction applied like that of the metal bands. It turned out that the tapes of the so established cables are no longer pressed in.

In der Zeichnung ist ein Ausführungsbeispiel eines Hochfrequenzkabels dargestellt. Der Leitera ist durch eine Wendel b aus Polystyrol von der konzentrischen Rückleitung c aus steilgängig gewickelten Kupferbändern getrennt. Über der Rückleitung c ist der Bleimanteld und die Drahtbewehrunge angebracht..In the drawing is an embodiment of a high frequency cable shown. The conductor a is separated from the concentric one by a helix b made of polystyrene Return line c separated from steeply wound copper strips. Above the return line c the lead jacket and the wire reinforcement are attached ..
