Description

Mantel für elektrisch isolierte Kabel Elektrische Kabel für Starkstrom- oder Schwachstromzwecke werden im allgemeinen mit einem Bleimantel ausgerüstet, der das Eindringen von Feuchtigkeit in die Kabelseele verhindert. Ein Nachteil des Bleimantels ist sein großes Gewicht. Es ist zwar schon bekannt, zum Zwecke der Gewichtsersparnis den Bleimantel durch eine wasserdichte Hülle aus nichtleitenden Kunststoffen zu ersetzen. Die bisher vorgeschlagenen Stoffe haben jedoch nicht die genügende chemische und mechanische Widerstandsfähigkeit und Wasserundurchlässigkeit gezeigt, die zum Aufbau einer hinreichend wasserdichten Hülle um das Kabel unbedingt erforderllich sind.Sheath for electrically insulated cables Electrical cables for heavy current or low-voltage purposes are generally equipped with a lead jacket, which prevents the penetration of moisture into the cable core. A disadvantage of the Lead jacket is its great weight. It is already known for the purpose of saving weight the lead sheath through a waterproof cover made of non-conductive plastics substitute. However, the substances proposed so far do not have sufficient chemical properties and shown mechanical resistance and impermeability to the It is absolutely necessary to build a sufficiently waterproof cover around the cable are.

Es ist zwar schon vorgeschlagen worden, nichtvulkanisierte Polymerisate d=r Acrylsäure, deren Derivate oder Homologen, allein oder im Gemisch, gegebenenfalls mit Zusatzstoffen als Isolierung für elektrische Leitungen zu verwenden.It has been proposed to use non-vulcanized polymers d = r acrylic acid, its derivatives or homologues, alone or in a mixture, if appropriate to be used with additives as insulation for electrical cables.

Gemäß der Erfindung erfolgt demgegenüber die Verwendung der wasserunlöslichen Polymerisate von Acrylsäureverbindungen, beispielsweise der Polymerisate der Acrylsäureester oder deren Homologen, die für sich oder in Mischung miteinander gebildet sind, als nichtleitender wasserdichter Mantel für elektrisch isolierte Kabel an Stelle eines Bleimantels. Diese Stoffe haben den besonderen Vorteil, daß sie außerordentlich beständig sind gegen Angriffe von Säuren o. dgl. und gegen alle anderen chemischen Einflüsse, denen eine Kabelumhüllung unterworfen sein kann. Außerdem bilden sie, auf die Kabelseele aufgebracht, eine hinreichend wasserdichte und wasserunlösliche Hülle. Falls die aus den obengenannten Stoffen gebildete wasserundurchlässige Hülle nicht die genügende Steifigkeit besitzen sollte, empfiehlt es sich, sie nicht unmittelbar auf die Kabelseele zu legen, sondern eine Zwischenschicht zwischen ihr und der Kabelseele, bestehend aus Gummi o. dgl., zu verwenden.According to the invention, on the other hand, the water-insoluble ones are used Polymers of acrylic acid compounds, for example the polymers of acrylic acid esters or their homologues, which are formed by themselves or as a mixture with one another, as non-conductive waterproof jacket for electrically insulated cables in place of one Lead jacket. These substances have the particular advantage that they are extraordinary are resistant to attack by acids or the like and to all other chemical substances Influences to which a cable sheathing can be subjected. They also form applied to the cable core, a sufficiently waterproof and water-insoluble one Covering. If the waterproof cover formed from the above-mentioned substances should not have sufficient rigidity, it is advisable not to use it immediately to put on the cable core, but an intermediate layer between it and the cable core, Consisting of rubber or the like. To be used.

Zur Herstellung der erfindungsgemäßen wasserdichten Hülle kann man die genannten Polymerisationsprodukte in beliebiger Weise auf die Kabelseele aufbringen; besonders zweckmäßig ist es, Bänder, die aus den Polymerisaten bestehen, zu einer dichten und lückenlosen Bandage um die Kabelseele zu wickeln. Bei vielen der genannten chemischen Stoffe sind dabei besondere Klebe- und Lösungsmittel, um die Fugen innerhalb der Bewicklung abzudichten, überflüssig, da die einzelnen Windungen der Bandage schon ohne besonderes Bindemittel durch den Druck des Aufbringens fest miteinander verbunden werden.For the production of the waterproof cover according to the invention one can apply said polymerization products in any way to the cable core; It is particularly useful to use tapes made from the polymers exist, to wrap around the cable core to form a tight and gapless bandage. With many of the chemical substances mentioned are special adhesives and solvents to to seal the joints within the wrapping is superfluous because the individual turns of the bandage already without any special binding agent due to the pressure of the application be connected to each other.
