Aufgabe der Erfindung ist die selbsttätige Atdichtung von Kabelmänteln an Beschädigungsstellen. Bei der Lösung dieser Aufgabe wird von der genannten Mikroverkapselung Gebrauch gemacht. Gegenstand der Erfindung ist ein selbstdichtender Kabelmantel tUr Fernfelde- oder Starkstromkabel mit den Kennzeichen, da8 an der Innenseite des Kabelmantels mindestens eine mikroverkapselte Flüssigkeit angeordnet ist, die die Eigenschaft hat, nach Enykapselung durch chemische Reaktion in den festen Zustand überzugehen. ?.B. kann man die beiden zur Herstellung von Polyurethanscha= üblichen Komponenten getrennt mikroverkapselt in erforderlichenisah:@ngsverhältni@a unter dem Kabelmanr;el anordnen. In Falle einer des Kabelmantels (z.B. d einen Pickenhieb) werden direkt und/oder durch eindringende ?ouchtigkeit Kapseln der beiden @oapanentontröpfcb.en geZ5fnet bzw. gelbat, so das Me freigelegten Morgen sitelnandes reagieren und der gebildete Pclyorethensehaum die ussUcht gewordene Stelle den äabelmantele selbsttätig abdichtet Entsprechend Wirken andere an sich bekalnte Flüssigkeiten, die allein oder in entsprechenden Mischumgs ierhäl tnissen izata:c übergeng in den Festzustand reagieren, Nenn der Vez-kapselunge-_mu®temd aufgehoben wird. The object of the invention is the automatic sealing of cable sheaths at points of damage. In solving this problem , use is made of the mentioned microencapsulation. The invention is a self-sealing cable sheath TUR Fernfelde- or power cables with the indicator, DA8 a microencapsulated liquid is arranged on the inside of the cable sheath at least, which has the property to pass through a chemical reaction in the solid state after Enykapselung. ? .B. the two components commonly used for the production of polyurethane can be arranged separately, microencapsulated in the required proportions under the cable jacket. In the case of one of the cable sheaths (e.g. a pecking stroke), the capsules of the two @ oapanenton droplets are opened or yellowed directly and / or by penetrating moisture, so that the exposed morning reacts independently and the plyorethensehaum formed, the area that has become the outer jacket automatically Accordingly, seals work other bekalnte se liquids, alone or in appropriate Mischumgs ierhäl tnissen izata: c übergeng react in the solid state, nominal VEZ-kapselunge-_mu®temd is canceled.

Schaumstoffbildende Flüssigkeiten haben Bai Rahmen der Erfindung den Vorzug, daß sie ein durch Beschädigung des Kabelmantels an tstandenee Lach besser ausfüllen als Flüssigkeiten, die nach dem Obergang in den Festmustand praktisch kein größeres Volumen als vorher einnehmenYou can search for the.Flüssigkditsmikr2kapseln inesrr @ ersa. Bands embedded to cf -.- * e ^ äabelseels harwm Anoz dunes or without these bands stick to the surface of the cable rope. Foam-forming liquids have the advantage within the scope of the invention that they fill a pool due to damage to the cable jacket better than liquids which after the transition to the solid state practically do not take up any larger volume than before
