Abstract

Es wird ein isolierter elektrischer Leiter mit Funktionserhalt im Brandfall beschrieben, bestehend aus einem metallischen Leiter, einer auf den Leiter aufgebrachten ersten Glas und/oder Glimmer enthaltenden Schicht und einer die erste Schicht umgebenden zweiten Kunststoffschicht, wobei die erste Schicht aus zumindest zwei längseinlaufend auf den Leiter aufgebrachten Bändern (2,3) aus Glas und/oder Glimmer besteht, deren Breite so gewählt ist, daß die Bänder (2,3) einander um mindestens 50 % überlappen.

Figure 00000001
An insulated electrical conductor with functional integrity in the event of a fire is described, consisting of a metallic conductor, a first layer of glass and / or mica applied to the conductor and a second plastic layer surrounding the first layer, the first layer consisting of at least two running in longitudinally on the Conductor applied tapes (2,3) made of glass and / or mica, the width of which is selected so that the tapes (2,3) overlap each other by at least 50%.
