Abstract

Zur Herstellung eines brandsicheren elektrischen Kabels oder einer brandsicheren elektrischen Leitung mit zumindest einer einen elektrischen Leiter (3) und eine Isolierung (9) aufweisenden Ader (13), wenigstens einer Schicht (5) eines flammhemmenden Materials (7) und einem Außenmantel (11) wird auf eine mit der Schicht (5) flammhemmenden Materials (7) zu versehene Oberfläche ein Klebemittel (23) aufgebracht und im gleichen Arbeitsgang die Oberfläche mit dem flammhemmenden Material (7) beflockt. Durch dieses Verfahren sind auf einfache Art und Weise und mit hoher Fertigungsgeschwindigkeit brandsichere elektrische Kabel und Leitungen herstellbar, die im Brandfall noch über eine längere Zeit funktionstüchtig bleiben (Fig. 4).

Figure 00000001
For the production of a fire-proof electrical cable or a fire-proof electrical line with at least one wire (13) having an electrical conductor (3) and insulation (9), at least one layer (5) of a flame-retardant material (7) and an outer jacket (11) an adhesive (23) is applied to a surface to be provided with the layer (5) of flame-retardant material (7) and the surface is flocked with the flame-retardant material (7) in the same operation. This method enables fire-safe electrical cables and lines to be produced in a simple manner and at high production speed, which remain functional for a long time in the event of a fire (FIG. 4).
