Definitions
- the metal oxide catalytic coating will be formed of a non-passivatable material, such as a noble metal belonging to the platinum group, including platinum, iridium, rhodium, ruthenium, palladium, osmium or mixtures thereof, more preferably, an oxide of one of these materials or a mixture thereof or other transition metals are used.
- a non-passivatable material such as a noble metal belonging to the platinum group, including platinum, iridium, rhodium, ruthenium, palladium, osmium or mixtures thereof, more preferably, an oxide of one of these materials or a mixture thereof or other transition metals are used.
- the cable and tubing are passed through the anode until a segment of the cable previously stripped of its insulating sheath and supplied with a highly conductlve split collar having a thickness substantially equal to the combined thickness of the cable insulation and elastomeric tubing is underneath one of the bushings and at least one piece of the tubing is located on at least one side of the stripped cable segment and underneath at least one of the bushings.

Claims (16)
- Verfahren zur Herstellung einer versiegelten elektrischen Verbindung zwischen anodisch unlöslichen, röhrenförmigen Ventilmetall-Anoden und einen korrodierbaren Kern eines Stromversorgungskabels, das durch einen Isoliermantel isoliert ist, wobei das Verfahren die folgenden Schritte umfaßt:a) Anbringen einer Anzahl duktiler Metallhülsen über der röhrenförmigen Ventilmetall-Anode, die eine korrosionsbeständige Außenfläche aufweist;b) Durchführen des isolierten Kabels durch die röhrenförmige Anode bis zu einem Segment des Kabels, von dem zuvor die Isolierschicht abgezogen wurde und das eine geschlitzte Manschette aus hochleitfähigem Metall um den leitfähigen Kern des Kabels aufweist, wobei sich die Manschette unter einer der Hülsen befindet und;c) plastisches Verringern des Umfangs der Anode im Bereich der außen befindlichen Hülsen durch Kaltstauchen der Ventilmetall-Anode um die im Bereich einer der Hülsen auf dem leitfähigen Kern angeordnete geschlitzte Manschette und im Bereich der Hülse(n), die auf wenigstens einer Seite der im Bereich der geschlitzten Manschette befindlichen Hülse angeordnet ist(sind),dadurch gekennzeichnet, daß das Verfahren zwischen dem Schritt a) und dem Schritt b) außerdem folgenden Schritt umfaßt:
Durchführen des isolierten Stromversorgungskabels durch wenigstens ein Stück eines Elastomerschlauchs, dessen Innendurchmesser etwas größer als der Durchmesser des Isoliermantels und dessen Außendurchmesser etwas kleiner als der Innendurchmesser der Anode ist; worin im nachfolgenden Schritt b) das Isolierkabel und der Elastomerschlauch oder die -schläuche so durch die röhrenförmige Anode geführt werden, daß wenigstens ein Stück des Schlauchs auf wenigstens einer Seite des abgezogenen Kabelsegments und unter wenigstens einer der Hülsen angeordnet ist, wobei die Dicke der Manschette im wesentlichen gleich der Gesamtdicke der Kabelisolierung und des Elastomerschlauchs ist; und worin im Schritt c) das Kaltstauchen der Ventilmetall-Anode im Bereich der wenigstens auf einer Seite der im Bereich der geschlitzten Manschette befindlichen Hülse angeordneten Hülse(n) direkt um das Stück oder die Stücke des Schlauchs bewirkt wird. - Verfahren gemäß Anspruch 1, worin die außen befindlichen, duktilen Metallhülsen aus einem anodisch löslichen Metall aus der Gruppe bestehen, die Kupfer, Aluminium, Eisen, Kupfer-Nickel-Legierungen und deren Mischungen umfaßt.
- Verfahren gemäß Anspruch 1, worin drei Hülsen über der Anode angeordnet sind, wobei eine im wesentlichen zentral auf der Anode und die übrigen in der Nähe der beiden entsprechenden Enden der Anode angeordnet sind.
- Verfahren gemäß Anspruch 1, worin das Stromversorgungskabel mit einer doppelten Isolierschicht isoliert ist, die eine Außenschicht aus Polyethylen mit hohem Molekulargewicht und eine Innenschicht aus Polyvinyliden-Difluorid oder Fluorpolymer aufweist.
- Verfahren gemäß Anspruch 1, worin das Stromversorgungskabel eine Isolierung aus Polyethylen mit hohem Molekulargewicht aufweist.
- Verfahren gemäß Anspruch 1, worin der Elastomerschlauch aus dienmodifiziertem Ethylen-Propylencopolymer-Kautschuk besteht.
- Verfahren gemäß Anspruch 1, worin die Manschette aus silberplattiertem Kupfer besteht.
- Verfahren gemäß Anspruch 1, worin die Anode aus Titan besteht und mit einer katalytischen Schicht aus einem leitfähigen Mischmetalloxid beschichtet ist.
- Verfahren gemäß Anspruch 2, worin die Hülsen nach Schritt c) durch anodisches Zersetzen während der Anfangsphase des Anodenbetriebs unter Betriebsbedingungen entfernt werden.
- Verfahren gemäß Anspruch 2, worin die Hülsen nach Schritt c) vor der Benutzung mechanisch entfernt werden.
- Zwischenanode, die nach dem Verfahren gemäß Anspruch 3 erhältlich ist.
- Endanode, die nach dem Verfahren gemäß einem der Ansprüche 1, 2 oder 4 bis 8 erhältlich ist, worin eine erste Hülse im wesentlichen zentral auf der Anode und eine zweite Hülse an einem Ende der Anode angeordnet sind, wobei das abschließende Ende der Anode versiegelt ist.
- Endanode gemäß Anspruch 12, worin eine Endkappe auf das abschließende Ende geschweißt ist.
- Endanode gemäß Anspruch 13, worin die Endkappe aus beschichtetem Titan besteht.
- Endanode gemäß Anspruch 11, worin ein Stab aus nicht elastomerem Kunststoff, dessen Durchmesser im wesentlichen gleich dem Innendurchmesser des Elastomerschlauchs entspricht, in die Röhre getrieben ist und worin die Titananode am Ort der Einführung des Stabs gepreßt ist.
- Verwendung einer nach dem Verfahren gemäß einem der Ansprüche 1 bis 10 erhältlichen Anode für den kathodischen Korrosionsschutz metallischer Strukturen.
