Description
Die Erfindung betrifft einen metallischen Mantel für ein elektrisches Kabel mit einem Verhältnis von Innendurchmesser Di zu Außendurchmesser Da von mindestens 0,90.The invention relates to a metallic sheath for an electrical cable with a ratio from inner diameter Di to outer diameter Da of at least 0.90.
Metallische Mäntel als Schutz für elektrische Kabel sind seit langem bekannt. Insbesondere bei erdverlegten Kabeln soll der Metallmantel die Isolierung vor dem Eindringen von Feuchtigkeit schützen.Metallic sheaths for protecting electrical cables have long been known. Especially at underground cables, the metal sheath is designed to insulate against moisture protect.
Eine Form eines metallischen Mantels besteht in einem Bleimantel, der über die Isolierschicht extrudiert wird. Der Bleimantel hat den großen Vorteil, daß Fehlerströme gut abgeleitet werden können. Insbesondere die Durchverbindung zweier Bleimäntel ist sehr einfach durchzuführen. Der Bleimantel schützt das Kabel vor Feuchtigkeit, behindert dennoch nicht die Biegbarkeit des Kabels. Die Wanddicke des Bleimantels beträgt in etwa 10 % des Außendurchmessers. Aufgrund ökologischer Forderungen soll der Bleimantel in Zukunft durch andere Metallmäntel mit identischen Eigenschaften ersetzt werdenOne form of a metallic sheath consists of a lead sheath over the insulating layer is extruded. The lead sheath has the great advantage that leakage currents are dissipated well can. The connection of two lead coats in particular is very easy to carry out. The lead sheath protects the cable from moisture, but does not hinder the flexibility of the Cable. The wall thickness of the lead jacket is approximately 10% of the outside diameter. Due to ecological requirements, the lead jacket should in future be covered by other metal jackets be replaced with identical properties
Als Alternative zum Bleimantel wurde der sogenannte Wellmantel entwickelt. Hierbei handelt es sich um ein längsnahtgeschweißtes Metallrohr, welches nach der Schweißung mit einer schraubenlinien- oder ringförmigen Wellung versehen wird. Durch die Wellung erhält der relativ dünnwandige Mantel eine höhere Festigkeit sowie eine bessere Biegbarkeit. Als Werkstoffe für den Wellmantel haben sich zunächst Kupfer, später hauptsächlich Stahl durchgesetzt, nachdem das Problem der Korrosion gelöst war.The so-called corrugated jacket was developed as an alternative to the lead jacket. This is what it is about is a longitudinally welded metal pipe, which after welding with a helical or annular corrugation is provided. The corrugation gives the relative thin-walled jacket a higher strength and better flexibility. As materials for the corrugated sheath initially copper, later mainly steel, after the problem of corrosion was solved.
Beim Wellmantelverfahren wird ein längseinlaufendes Metallband mittels eines Formwerkzeugs zu einem Rohr geformt, das Rohr längsnahtgeschweißt und gewellt. Das Metallband wird zu einem Rohr mit größerem Durchmesser als der Durchmesser der in das Schlitzrohr eingeführten Kabelseele geformt, um eine Beschädigung der Kabelseele durch den Lichtbogen der Schweißeinrichtung zu vermeiden. Beim Wellen wird die Kabelseele durch die beim Wellvorgang entstehenden Wellentäler gegriffen.In the corrugated jacket process, a longitudinally running metal strip is made using a molding tool formed into a tube, the tube was longitudinally welded and corrugated. The metal band becomes too a tube with a larger diameter than the diameter of the inserted into the slotted tube Cable core shaped to prevent damage to the cable core by the arc of the Avoid welding equipment. When waves, the cable core is by the Corrugated process arising troughs gripped.
Aus der CA-PS 603 527 ist ein gewellter Metallmantel für elektrische Kabel bekannt, bei welchem der Innendurchmesser Di des gewellten Rohres zwischen 0,75 und 0,85 des Außendurchmesser Da des gewellten Rohres liegt. Der Abstand zweier benachbarter Wellenberge beträgt 0,15 bis 0,25 von Da und die Wanddicke liegt bei 0,005 bis 0,02 von Da.From CA-PS 603 527 a corrugated metal sheath for electrical cables is known which the inside diameter Di of the corrugated tube between 0.75 and 0.85 of Outside diameter because of the corrugated pipe. The distance between two neighboring ones Wave crests are 0.15 to 0.25 of Da and the wall thickness is 0.005 to 0.02 of Da.

Ein drehbar in einem drehangetriebenem Wellerkopf angeordneter Wellerwälzring wälzt sich auf der Oberfläche des geschweißten Rohres ab und drückt, da er exzentrisch im Wellerkopf gelagert ist, die Rohrwand ein. Mit diesem Verfahren lassen sich Rohre mit einem Verhältnis von Außendurchmesser Da zu Wanddicke s von weniger als 30 und mehr als 100 nicht ohne besondere Vorkehrungen herstellen.The corrugated process is a process such as that described in DE-AS 1086314. A rotatably arranged in a rotary driven well head Weller roller ring rolls on the surface of the welded pipe and presses because it is mounted eccentrically in the well head, the tube wall. With this procedure you can Pipes with a ratio of outside diameter Da to wall thickness s of less than 30 and not manufacture more than 100 without special precautions.

Durch geeignete Auswahl des Werkstoffs für den Mantel, bzw. durch gezielte Beschichtung ist der Mantel gegen Korrosion geschützt.By suitable selection of the material for the jacket, or by targeted coating the jacket protected against corrosion.
Der Kabelmantel ist gut biegbar und weist eine hervorragende Beulfestigkeit, bzw. Querstabilität auf. Durch die geeignete Auswahl von Wellenabstand, Welltiefe bei vorgegebenem Außendurchmesser kann die Wanddicke s bis auf ein Maß gesenkt werden, welches für die elektrischen Eigenschaften erforderlich ist.The cable sheath is easy to bend and has excellent dent resistance, or Lateral stability. Through the appropriate selection of shaft spacing, shaft depth at given the outside diameter, the wall thickness s can be reduced to a level which is required for the electrical properties.

und dem Schlitz des Schlitzrohres 2 ein ausreichender Spalt verbleibt, damit die Kabelseele 4
keinen Schaden erleidet, wenn der Schlitz mittels der Schweißvorrichtung 5 - einer
Lichtbogenschweißeinrichtung oder einer Laserschweißeinrichtung - geschlossen wird. Das
geschweißte Rohr 6 wird dann einer Wellvorrichtung 7 zugeführt, die aus dem geschweißten,
glatten Rohr 6 ein Wellrohr 8 herstellt. Die Wellung des Wellrohres 8 ist derart, daß die
Kabelseele 4 von der Wellung gefaßt wird, d. h. die Wellentäler des Wellrohres 8 liegen auf der
Kabelseele 4 auf. Ein solches Verfahren ist im Prinzip aus der DE-AS 1086314 bekannt.A

Mantel 10 ersetzt den Bleimantel 9, ohne daß die geometrischen Abmessungen geändert werden
müssen. Ein mit dem erfindungsgemäßen Mantel 10 versehenes Kabel kann also wie das
bekannte Bleimantelkabel in Kabelkanäle eingezogen werden und dabei ein bisher verwendetes
Bleimantelkabel ersetzen. The corrugation of the
