(Reichstrom-Hochspannungskabel(Reichstrom high voltage cable
In neuerer Zeit haben sich für die Isolierung und Ummantelung elektrischer Kabel weitgehend hochpolymere Kunststoffe eingeführt. Besonders Polyäthylen wird wegen seiner guten dielektrischen Eigenschaften in Verbindung mit seiner geringen Feuchtigkeitsempfindlichkeit für die Isolierung bevorzugt, insbesondere wenn es sich um Kabel handelt, die für Verlegung in feuchter Umgebung oder Wasser bestimmt sind. Die Neuerung geht von der Erkenntnis aus, daß Polyäthylen wegen seines besonders großen Isolationswiderstandes und seiner besonders kleinen Dielektrizitätskonstante in Verbindung mit seiner kristallinen Überstruktur besonders anfällig gegen Vorentladung ist, die von Störstellen im Material ausgehen, und daher für Kabel für Hohe Gleichspannung wenig geeignet ist.More recently, insulation and sheathing have become popular electrical cables largely introduced high polymer plastics. Particularly polyethylene is used because of its good dielectric properties in connection with its low Moisture sensitivity preferred for insulation, especially when it comes to cables that are to be laid intended in a damp environment or in water. The innovation is based on the knowledge that polyethylene because of its particularly large insulation resistance and its particularly low dielectric constant in connection with its crystalline superstructure, particularly susceptible to pre-discharge that originate from imperfections in the material and is therefore not very suitable for cables for high DC voltage.
Von dieser Erkenntnis ausgehend, sieht die Feuerung für Gleiohstrom-Hochspannungskabel, die für Verlegung in feuchter Umgebung oder Wasser geeignet sind, insbesondere also für Seekabel, vor,On the basis of this knowledge, the furnace for Gleiohstrom high-voltage cables, which are suitable for laying in a damp environment or in water, in particular for submarine cables,

daß die mit einer Abschirmung zur Begrenzung des elektrischen leides versehene Isolierung aus einer Mischung auf Basis von Polyvinylchlorid und der als Feuchtigkeitsschutz dienende geschlossene Mantel» über dem eine z,B. zugfeste Bewehrung angeordnet sein kann, aus Polyäthylen bestehen. Ein solches Kabel ist höheren Dauerbeanspruchungen mit Gleichspannung gewachsen, als dies ein Kabel mit Polyäthylen-Isolierung wäre, da Polyvinylchlorid unter Ausschluß von Feuchtigkeit eine größere Dauer-Gleiehspannungsfestigkeit besitzt als Polyäthylen,that the insulation, which is provided with a screen to limit the electrical damage, is made of a mixture based on polyvinyl chloride and the closed jacket, which serves as moisture protection, is made of polyethylene, over which a tensile reinforcement, for example, can be arranged. Such a cable can withstand higher continuous loads with direct voltage than a cable with polyethylene insulation would be, since polyvinyl chloride has a greater permanent equilibrium strength than polyethylene when moisture is excluded,
In der Figur ist beispielsweise ein Kabel gemäß der Neuerung im Schnitt dargestellt. Der Leiter 1 ist mit einer Isolierhülle 2 aus einer Mischung auf Basis von Polyvinylchlorid versehen, über der* eine Abschirmung 3, beispielsweise in Form einer Bespinnung aus einem dünnen Kupferband, angeordnet ist. Darüber liegt ein geschlossener Mantel 4 aus Polyäthylen als Feuchtigkeitsschutz. Über dem Mantel ist eine Bewehrung 5 aus zugfesten Drähten angeordnet. . . ' .In the figure, for example, is a cable according to the innovation shown in section. The conductor 1 is with an insulating sleeve 2 made of a mixture based on polyvinyl chloride, over which a shield 3, for example in In the form of a spinning made of a thin copper band, arranged is. Above it is a closed jacket 4 made of polyethylene as protection against moisture. There is reinforcement 5 over the jacket arranged from tensile wires. . . '.
