Description

Bei elektrischen Kabeln mit doppeltem Bleimantel hat man zwischen den beiden Bleimänteln bereits eine Einlage angebracht, um etwa in den Bleimänteln vorhandene Poren zu dichten, und man hat auch bereits in besonderen Fällen die Einlage benutzt, um die beiden Bleimantel gegeneinander zu isolieren. Eine derartige Isolierung der beiden Bleimäntel ist besonders dann erforderlich, wenn es sichWith electrical cables with a double lead sheath, you have lead sheaths between the two an insert has already been attached to seal pores in the lead sheaths, for example, and one also has special ones Cases the insert is used to isolate the two lead sheaths from each other. Such insulation of the two lead sheaths is particularly necessary if it is

ίο darum handelt, einen Schutz gegen die zerstörende Wirkung vagabundierender Ströme zu haben. Die Isolierung soll dabei erfindungsgemäß in der Weise geschehen, daß die zwischen den beiden Mänteln befindliche Einlage aus Schichten verschiedener Stoffe aufgebaut ist und eine oder ein Teil dieser Schichten durch Papier oder Faserstoff, der andere Teil dieser Schichten durch Compound oder compoundähnliche Masse gebildet wird.ίο is about a protection against the destructive To have the effect of stray currents. According to the invention, the insulation should be used done in such a way that the insert located between the two coats from Layers of different substances is built up and one or a part of these layers through Paper or pulp, the other part of these layers by compound or compound-like Mass is formed.

In der Zeichnung sind zwei Ausführungsbeispiele veranschaulicht. In beiden Fällen sind α die beiden Bleimäntel, δ Schichten aus Compound oder compoundähnlicher Masse und c Schichten aus gegen Feuchtigkeit und Säuren widerstandsfähig gemachtem Papier oder Faserstoff. Nach Abb. 1 und 2 liegt einfach eine Schicht c zwischen zwei Schichten b ] nach Abb. 3 und 4 wechselt eine Mehrzahl von Schichten c mit Schichten δ derart ab, daß gleichfalls wieder die Schichten c zwischen den Schichten δ eingeschlossen sind.Two exemplary embodiments are illustrated in the drawing. In both cases, α are the two lead sheaths, δ layers of compound or compound-like mass and c layers of paper or fiber made resistant to moisture and acids. According to Fig. 1 and 2, a layer c is simply between two layers b] according to Fig. 3 and 4, a plurality of layers c alternate with layers δ in such a way that the layers c are also included again between the layers δ.

Durch diese Anordnung erhält man einen sehr vollkommenen Schutz sowohl gegen die zerstörende Einwirkung von Feuchtigkeit und Säuren als auch gegen ein Übergreifen vagabundierender Ströme auf den inneren Bleimantel.This arrangement gives a very complete protection against both destructive effects of moisture and acids as well as against spreading stray Currents on the inner lead jacket.
