Description

Mit Bohaumstoff isolierte elektrische Leitung oder Ader und Verfahren zu deren Herstellung Bei mit Schaumstoff isolierten Leitungen oder Adern tritt die Schwierigkeit auf, da# die Isolierung an ihrer Oberfläche porige Unebenheiten aufweist, die bevorzugte Angriffspunkte für mechanische Beschädigungen darstellenl Dies tritt besouders dann ein, wenn mit Schaumstoff isolierte Adern weiter verseilt werden und beim Durchlaufen des Verseilnippels leicht Besohädigungen ausgesetzt sind. Electrical line or wire and process insulated with bohaumstoff for their production In the case of cables or wires insulated with foam, the Difficulty arises because # the insulation has porous unevenness on its surface, represent the preferred points of attack for mechanical damage. This occurs especially when cores insulated with foam are stranded further and are easily exposed to damage when passing through the stranding nipple.

Es ist bereits bekannt, bei schaumstoffisolierten K@axialleitern die Schaumstoffisolierung auf den Innenleiter zwecks Vermeidung von durch die Poren bedingten Feldinkom@genitäten über eine dünne massive Iselierstoffschi@ht aufzubringen. Weiterhin ist vorgeschlagen worden, die Oberfläche der Isolierung itt Fetten oder Ölen su imprägnieren, um das Eindringen von Feuchtigkeit na unterbinden.It is already known in the case of foam-insulated K @ axial conductors Foam insulation on the inner conductor to avoid through the pores to apply the conditional field inconsistencies via a thin, massive layer of insulating material. It has also been proposed that the surface of the insulation be itt greases or Impregnate oils to prevent moisture from penetrating.

Die Vorliegende Erfindung besi@ht sich auf mit Schaumstoff, insbesondere aus P@lyäthylen isolierte elektrische Leitungen oder Adern, die sich von den bisher b@kannten dadurch unterscheiden, das die Oberfläche der Is@lierung aus einer nicht aufgeschäumten Schicht des gleichen oder einesw anderen Isolierstoffes best@ht.The present invention relates to foam, in particular Electrical cables or wires insulated from P @ lyäthylen, which differ from the hitherto b @ knew how to differentiate that the surface of the insulation from one did not foamed layer of the same or a different insulating material.

Durch die Besender@ Ausbildung der Ob@@fläche werden die eingang@ besohri@benen Schwierigkeiten b@hoben, ohne den elektrischen Wert der Isolation zu beeinträchtigen.Through the training of the ob @@ area, the input @ problems discussed without affecting the electrical value of the insulation to affect.

Die Erfindung b@si@ht sich weiterhin nuf Verfahren sur Herstellung der vorstehend angegebenen Leitungen oder Adern.The invention is also based on a method of production the cables or wires specified above.

Nach des einen arfindungsgemä#en Verfahren wird naoh dei Herstellen der Schaumstoff@chicht diese itt einer weiteren ni@ht aufgeschäumten Schicht aus dem gleichen oder einem anderen Isolierstoff bedeckt, vorsugsweise überspritzt. Diese@ Verfahren erfordert entweder zwei Arbeit@gänge oder einen Arbeit@gang mit sirei Maschinen.According to one method according to the invention, the production is carried out the foam layer this from a further non-foamed layer covered with the same or a different insulating material, overmolded as a precaution. This @ procedure requires either two work @ steps or one work @ work with sirei machines.

@ach dem anderen Verfahren gemä# der Erfindung wird eine Schaumstoff@chicht aufgespritzt und sofort naoh dem Verlassen der Spritzmaschine an ihrer Oberlfäche einer KUhlbehandlung oder @ärmebehandlung, z. B. im Durchlaufverfahren, unterworfen. Dabei vrliert die Oberfläche des Schaumstoff@ ihre Schaumstuktur und wird massiv.According to the other method according to the invention, a foam layer is formed sprayed on and immediately after leaving the spraying machine on its surface a cooling treatment or heat treatment, e.g. B. in the continuous process, subjected. In the process, the surface of the foam vrels its foam structure and becomes solid.
