Description
Elektrischer Leiter oder elektrisches Kabel Bei elektrischen Leitern oder Kabeln, bei denen es auf geringe frequenzabhängige Verluste ankommt, zum Beispiel bei Kabeln für Fernsehzwecke, ist es bekannt, als Isolierstoff Polyrisobutylen in gummiartiger Beschaffenheit zu verwenden. Es hat sich nun bei derartigen Leitern gezeigt, daß nach einer gewissen Betriebszeit eine Verlagerung der Leiter im Isolierstoff eintritt. Die Erfindung bezweckt, eine solche Verlagerung durch Einlagen im Isolierstoff zu verhindern, die die Verluste des Isolierstoffes nicht erhöhen.Electrical conductor or cable For electrical conductors or cables where low frequency-dependent losses are important, for example in cables for television purposes, it is known to be used as an insulating material in polyrisobutylene rubbery texture to be used. It has now become the case with such ladders shown that after a certain period of operation a shift of the conductor in the insulating material entry. The aim of the invention is to provide such a shift by means of inserts in the insulating material to prevent that do not increase the losses of the insulating material.
Erfindungsgemäß ist die Verlagerung der Leiter mit einer Isolierung aus Polyisobutylen durch Einlagen aus Glasfäden oder Glasgeweben, gewirkten oder geklöppelten Glasbändern unterdrückt. Die Verwendung von Glasgeweben zur Isolierung elektrischer Leiter ist an sich bekannt, und zwar an Stelle von Papier o. dgl., um eine möglichst temperaturbeständige Isolierung zu erzielen. Durch die bekannte Verwendung ist jedoch weder die Anordnung von Einlagen zur Verhinderung der Verlagerung der Leiter mit Isolierung aus Polyisobutylen noch die Verwendung von Glasgeweben für diese Einlagen nahegelegt.According to the invention, the relocation of the conductor with insulation made of polyisobutylene with inserts made of glass threads or woven glass fabrics, knitted or oppressed glass ribbons. The use of glass fabrics for insulation electrical conductor is known per se, in place of paper or the like, to achieve the most temperature-resistant insulation possible. By the well-known However, neither use is the arrangement of deposits to prevent dislocation the conductor with insulation made of polyisobutylene nor the use of glass fabrics suggested for these deposits.
Ein Ausführungsbeispiel der Erfindung zeigt die Zeichnung. Hierin ist der elektrische Leiter mit i bezeichnet. Der Leiter ist von einer Schicht 2 aus Polyisobutylen umgeben, die sich innerhalb einer Hülle 3 aus mit Polyisobutylen getränkten Glasgeweben befindet. Diese Hülle verhindert die Verlagerung des Leiters gegenüber der äußeren Isolierschicht 4. aus Polyisobutylen, die ihrerseits wiederum von einer Schicht getränkter Glasgewebe umgeben ist.The drawing shows an embodiment of the invention. Here in the electrical conductor is denoted by i. The conductor is of a layer 2 surrounded by polyisobutylene, which is within a shell 3 made of polyisobutylene soaked glass fabric is located. This sheath prevents the conductor from shifting opposite the outer insulating layer 4. made of polyisobutylene, which in turn is surrounded by a layer of soaked glass fabric.
