Description

Hochwertige elektrische LeitungHigh quality electrical line

Die Erfindung betrifft eine biegsame, hochtemperaturbeständige elektrische Leitung mit einer Isolierschicht aus Glimmer.The invention relates to a flexible, high temperature resistant electrical Cable with an insulating layer made of mica.

Elektrische Leitungen mit Isolierschichten aus Glimmer sind an sich bekannt, vergleiche z.I3. DT-OS 25 51 568. Die bekannten Leitungen sind jedoch aufgrund der brennbaren Silikonharz-Bestandteile nur besc11rcinkt hitzebeständig, ihre mechanische Festigkeit ist, insbesondere in Verbindung mit h(5heren Temperaturen, mangelhaft und ihre 11erstellung infolge der Verwendung von Klebebändern aufwendig.Electrical lines with insulating layers of mica are in themselves known, compare e.g. I3. DT-OS 25 51 568. The known lines are due, however The flammable silicone resin constituents only reduce their heat resistance, their mechanical Strength is inadequate, especially in connection with higher temperatures and their production is expensive as a result of the use of adhesive tapes.

Der Erfindung liegt die Aufgabe zugrunde, eine biegsame, hochtemperaturbeständige elektrische Leitung zu schaffen, die einer Dauerbelastung durch Vibration und einer gleichzeitigen kurzfristigen Flammeinwirkung standhält.The invention is based on the object of a flexible, high-temperature-resistant to create electrical conduction that can withstand continuous exposure to vibration and a withstands simultaneous short-term exposure to flames.

Die genanntc Aufgabe wird erfindungsgemä.ß durch die in den Ansprüchen 1 oder 2 gekennzeichneten Merkmale gelöst. Devorzugte Ausführungen sind in den weiteren Unteransprüchen gekennzeichnet.The stated object is achieved according to the invention by what is stated in the claims 1 or 2 marked features solved. Preferred statements are in the following Characterized subclaims.

Die elektrischen Leitungen nach der Erfindung sind hervorragend für sogenannte Feuerwarnieitungen geeignet, da ihre Isolierung audi in der Flamme einen hohen Widerstand besitzt. Eine derartige Leitung hat die Aufgabe, im Falle eines Brandes, z.B. eines Triebwerks bei einem Flugzeug oder einem Panzer, eine Notschaltfunktion wahrzunehmen. Die Leitungen, welche diese höchst wichtige Funktion erfüllen, werden nach den strengen Vorschriften der amerikanischen Norm MIL-W-25038 geprüft oder nach entsprechenden Vorschriften der Triebwerk-Hersteller. Der Aufbau der erfindungsgemäßen elektrischen Leitung ist sehr widerstandsfähig gegen die in den genannten Anwendungsfällen auftretenden Vibrationsbelas tungen.The electrical cables according to the invention are excellent for So-called fire warning cables are suitable, as their insulation also creates a flame possesses high resistance. Such a line has the task, in the case of a Fire, e.g. an engine in an airplane or a tank, an emergency switch function perceive. The lines that perform this most important function will tested according to the strict regulations of the American standard MIL-W-25038 or according to the relevant regulations of the engine manufacturer. The structure of the invention electrical line is very resistant to the use cases mentioned occurring vibration loads.

In der Zeichnung sind zwei schematische Ausführungsbeispiele gezeigt, die im folgenden näher beschrichen werden. Es zeigen: Figur 1 eine erste erfindungsgemäße einadrige Leitung und Figur 2 eine zweite erfindungsgemäße zweiadrige Leitung.In the drawing, two schematic exemplary embodiments are shown, which are described in more detail below. They show: FIG. 1 a first according to the invention single-core line and FIG. 2 a second two-core line according to the invention.

Die Leitung nach Figur 1 besteht aus einem Leiterseil 1, das dUS 19 kupferdrähten mit Z-S-Drall zweilagig verseilt und dickvernickelt ist. über dem Leiterseil 1 ist eine erste eng anliewende Bandierung 2 aus Glimmerfolie (z.13. MICA PAPER CABLE TAPE 77925 von GE, USA bzw. MICA-Band der Firma Arisawa, Japan oder Cogebi, Belgien). Die Bandierung 2 ist mit Z-Drall und ca. 55 % Überlap)ung aufgebraciit. Darüber ist eine zweite Bandierung 3 aus der selben Glimmerfolie mit S-Drall und ca. 55 % Uberlappung eng anliegend aufgebracht. Die äußere Lage besteht aus einer Bandierung 4 aus PTFL'-Folie, die mit Z-Drall und ca. 55 % Uberlappung aufgebracht und gesintert ist.The line according to FIG. 1 consists of a conductor 1, the dUS 19 copper wires with Z-S twist are twisted in two layers and thickly nickel-plated. above that Conductor rope 1 is a first closely applied banding 2 made of mica foil (e.g. 13. MICA PAPER CABLE TAPE 77925 from GE, USA or MICA tape from Arisawa, Japan or Cogebi, Belgium). Banding 2 has a Z twist and approx. 55% overlap consumed. A second banding 3 made of the same mica foil is also on top S-twist and approx. 55% overlap applied tightly. The outer layer exists from a banding 4 made of PTFL 'film with a Z twist and approx. 55% overlap is applied and sintered.

Dic Leitung nach Figur 2 besteht aus zwei Leiterseilen 5 und 6, die zu Position 1 die Figur 1 erläutert. Jedes Leiterseil 5 bzw.The line according to Figure 2 consists of two conductor cables 5 and 6, the 1 explains FIG. 1 for item 1. Each conductor 5 resp.

6 ist mit einer eng anliegenden ersten Bandierung 7 bzw. 8 aus Glimmerfolie - wie zu Position 2 der Figur 1 erläutert - mit ca.6 has a tightly fitting first banding 7 or 8 made of mica foil - as explained for position 2 of Figure 1 - with approx.

70 t überlappung und Z-Drall versehen. Eine zweite Bandierung 9 bzw. 10 aus PTFE-Folie ist mit 55 % überlappung und S-Drall aufgebracht und gesintert. Beide bandierten Einzelleitungen sind mit Zwickelfüllungen 11 und 12 aus Glasfaserkordel oder dergleichen im Z-Drall verseilt und von einem Geflecht 13 aus dick-vernickeltem Kupferdraht mit ca. 85 % Bedeckung umgeben. Darüber erstreckt sich eine Bandierung 14 mit Z-Drall und ca. 55 % Uberlappung aus Glirnmerfolie, die entsprechend der Position 2 der Figur ausgebildet ist. Die äußere Ilülle ist als Bandierung 15 init S-Drall und ca. 55 % Uberlappung aus PTFE-Folie aufgebracht und gesintert.70 t overlap and Z-twist. A second banding 9 resp. 10 made of PTFE film is applied and sintered with 55% overlap and S-twist. Both banded individual lines have gusset fillings 11 and 12 made of fiberglass cord or the like twisted in Z-twist and by a braid 13 made of thick nickel-plated Surrounded by copper wire with approx. 85% coverage. Banding extends over it 14 with Z-twist and approx. 55% overlap made of mica foil, which corresponds to the Position 2 of the figure is formed. The outer shell is a banding 15 init S-twist and approx. 55% overlap made of PTFE foil applied and sintered.

Anstelle einer PTFE-Bandierung kann in beiden Beispielen auch ein Glasfasergeflecht, das mit hitzebeständigem Lack oder dergleichen getränkt und wärmebehandelt ist, verwendet werden.Instead of a PTFE banding, a Glass fiber braid that is impregnated with heat-resistant paint or the like and heat-treated is to be used.

Die ilerstellung der beschriebenen Leitungen kann in einem oder mehreren Arbeitsgängen - je nach Maschinen- bzw. Anlagekapazit.it - erfolgen.The lines described can be created in one or more Work steps - depending on the machine or plant capacity.
