Abstract

Es wird ein koaxiales Hochfrequenz-Kabel angegeben, das aus einem Innenleiter (1), aus einem denselben umgebenden Dielektrikum (2), das mineralisches Material als Abstandshalterung enthält, und aus einem über dem Dielektrikum (2) liegenden, konzentrisch zum Innenleiter (1) angeordneten, rohrförmigen Außenleiter (3) besteht. Zum Funktionserhalt im Brandfall ist die Abstandshalterung aus einer Kombination von thermoplastischem Isoliermaterial und mineralischem Material aufgebaut.A coaxial high-frequency cable is specified which consists of an inner conductor (1) a dielectric surrounding it (2), the mineral material as Contains spacer, and from a lying over the dielectric (2), There is a tubular outer conductor (3) arranged concentrically with the inner conductor (1). To the Functional maintenance in the event of fire is the spacer made of a combination of thermoplastic insulating material and mineral material.
