Description

Die Erfindung bezieht sich auf eine elektrische Leitung mit mindestens zwei aus von einer Isolierung umgebenen Leitern bestehenden Adern, die miteinander verseilt und von einem gemeinsamen elektrischen Schirm umgeben sind, über dem rundum eine Schicht aus Isoliermaterial angebracht ist ( EP 1 134 749 A1 ).The invention relates to an electrical line having at least two conductors surrounded by insulation conductors, which are stranded together and surrounded by a common electric screen, is mounted on the all around a layer of insulating material ( EP 1 134 749 A1 ).

Derartige Leitungen werden beispielsweise zur Übertragung nachrichtentechnischer Signale eingesetzt. Wichtig für solche Leitungen ist ein elektrisch wirksamer Schirm, der auch nach oftmaligem Biegen der Leitung seine Funktion unverändert beibehält. Von Bedeutung sind auch die Abmessungen der Leitungen, die beispielsweise dann möglichst klein sein sollen, wenn eine derartige Leitung in der Seele eines Starkstromkabels oder einer Starkstromleitung als Steuerungszwecken dienendes Zusatzelement angeordnet werden soll.Such lines are used for example for the transmission of telecommunications signals. Important for such lines is an electrically effective screen, which retains its function unchanged even after frequent bending of the line. Also of importance are the dimensions of the lines, which should be as small as possible, for example, if such a line in the soul of a power cable or a power line as control purposes serving additional element should be arranged.

Die eingangs erwähnte bekannte Leitung nach der EP 1 134 749 A1 weist zwei Adern auf, die eine beispielsweise aus Polyethylen (PE) oder Polypropylen (PP) bestehende Isolierung haben. Die beiden Adern Sie sind von einem aus komprimierbarem Isoliermaterial bestehenden Innenmantel umgeben. Über dem Innenmantel ist ein als Geflecht ausgebildeter, beispielsweise aus Kupferdrähten bestehender elektrischer Schirm angebracht, der von einer durch zwei aufgewickelte Folien aus Isoliermaterial gebildeten Schutzschicht umgeben ist. Die Isoliereigenschaften des Isoliermaterials der Adern sind nicht sehr hoch, so dass die Wandstärke der den Leiter umgebenden Isolierung relativ dick ausgeführt werden muß. Die eingesetzten Materialien PE und PP sind außerdem dann nicht geeignet, weil sie beim Aufbringen eines Gummimantels schmelzen, wenn eine solche Leitung in einem entsprechenden Starkstromkabel oder in einer Starkstromleitung angeordnet wird. Der Außendurchmesser der Leitung ist entsprechend groß. Hinzu kommt, dass die Drähte des für den Schirm eingesetzten Geflechts nach mehrmaligem Biegen der Leitung leicht brechen können, wodurch die elektrische Schirmung der Leitung zumindest verschlechtert wird.The initially mentioned known line after the EP 1 134 749 A1 has two wires, which have an example of polyethylene (PE) or polypropylene (PP) insulation. The two cores They are surrounded by an inner sheath made of compressible insulating material. Above the inner shell, a braided electrical, for example made of copper wires existing electric screen is mounted, which is surrounded by a formed by two wound films of insulating material protective layer. The insulating properties of the insulating material of the wires are not very high, so that the wall thickness of the insulation surrounding the conductor must be made relatively thick. The materials PE and PP used are also not suitable because they melt when applying a rubber sheath when such a line is placed in an appropriate power cable or in a power line. The outer diameter of the pipe is correspondingly large. In addition, the wires used for the screen Braid can easily break after repeated bending of the line, whereby the electrical shielding of the line is at least deteriorated.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Leitung so zu gestalten, dass sie bei verkleinertem Außendurchmesser auf Dauer elektrisch wirksam geschirmt ist.The invention has for its object to make the above-described line so that it is electrically effectively shielded with reduced outer diameter in the long term.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • dass die Isolierung der Adern aus einem verdrückungsarmen, vernetzten elastomeren Isoliermaterial besteht, dessen Isolationswiderstandskonstante bei Raumtemperatur größer als 4.000 MΩkm ist, und
  • dass der Schirm aus einem durch Metallisierung elektrisch leitfähig gemachten Vlies auf Basis von Polyamid besteht.
This object is achieved according to the invention characterized
  • that the insulation of the cores consists of a low-resistance, cross-linked elastomeric insulating material whose insulation resistance constant at room temperature is greater than 4,000 MΩkm, and
  • in that the screen consists of a polyamide-based non-woven made electrically conductive by metallization.

Das verdrückungsarme Isoliermaterial der Adern hat einen durch seine Isolationswiderstandskonstante definierten hohen Isolationswert, so dass die Wanddicke der Isolierung der Adern bei gleichbleibenden Isolationseigenschaften gegenüber Adern mit herkömmlichen Isoliermaterialien verkleinert werden kann. Entsprechende vernetzte elastomere Isoliermaterialien haben beispielsweise die Qualität 3GI3 nach DIN VDE 0207, Teil 20. Der Durchmesser einer Umhüllenden um derartig isolierte und miteinander verseilte Adern und damit der Außendurchmesser einer entsprechenden Leitung kann also insgesamt gegenüber Leitungen mit herkömmlich isolierten Adern vermindert werden. Der aus einem metallisierten Vlies bestehende Schirm stellt eine die Leitung rundum umgebende, nahezu lückenlose Hülle dar, die wegen des Vliesaufbaus einerseits flexibel und wegen des eingesetzten Materials Polyamid andererseits mechanisch sehr stabil ist. Dieser Schirm behält auch nach oftmaligem Biegen der Leitung seine Schirmwirkung unverändert bei, weil er keine Elemente enthält, die brechen können.The low-resistance insulating material of the cores has a high insulation value defined by its insulation resistance constant, so that the wall thickness of the insulation of the cores can be reduced while retaining the insulation properties with respect to cores with conventional insulation materials. Corresponding cross-linked elastomeric insulating materials, for example, have the quality 3GI3 according to DIN VDE 0207, Part 20. The diameter of an envelope to such insulated and stranded together cores and thus the outer diameter of a corresponding line can thus be reduced compared to lines with conventionally insulated wires. The existing of a metallized non-woven screen represents a line surrounding the surrounding, almost seamless shell that is flexible because of the fleece structure on the one hand and mechanically very stable because of the material used polyamide on the other hand. This screen maintains its shielding effect unchanged even after bending the wire many times, because it contains no elements that can break.

Das verdrückungsarme Isoliermaterial weist zusätzlich mit Vorteil eine Wärmedruckbeständigkeit von kleiner als 20 % auf, wenn dasselbe gemäß IEC 6081 1-3-1 bei 150 °C mit einer Prüfzeit von 1 Stunde (k = 0,6) geprüft wird. Der Wert der Wärmedruckbeständigkeit ist vorzugsweise kleiner als 10%.In addition, the low-resistance insulating material advantageously has a thermal resistance of less than 20% when tested in accordance with IEC 6081 1-3-1 at 150 ° C with a test time of 1 hour (k = 0.6). The value of the heat pressure resistance is preferably less than 10%.

Für die Metallisierung des aus Polyamid bestehenden Vlieses wird mit Vorteil Kupfer verwendet, das aus der Dampfphase heraus auf dem Vlies abgeschieden wird und dabei auch in dasselbe eindringt.Copper is advantageously used for the metallization of the nonwoven consisting of polyamide, which is deposited on the nonwoven from the vapor phase and thereby also penetrates into it.

Ausführungsbeispiele des Erfindungsgegenstandes sind in den Zeichnungen dargestellt.Embodiments of the subject invention are illustrated in the drawings.

Es zeigen:

  • Fig. 1 und 2 zwei Leitungen nach der Erfindung mit unterschiedlichem Aufbau im Schnitt.
  • Fig. 3 einen Schnitt durch ein elektrisches Kabel mit darin enthaltener Leitung nach der Erfindung.
Show it:
  • Fig. 1 and 2 two lines according to the invention with different structure in section.
  • Fig. 3 a section through an electrical cable with therein contained line according to the invention.

Die Leitung nach Fig. 1 hat zwei elektrische Adern 1 und 2, die miteinander verseilt sind. Jede der beiden Adern 1 und 2 hat einen vorzugsweise aus Kupfer bestehenden elektrischen Leiter 3 und eine denselben umgebende Isolierung 4. Als Isoliermaterial für die Isolierung 4 der beiden Adern 1 und 2 ist ein vernetztes elastomeres Isoliermaterial eingesetzt, dessen Isolationswiderstandskonstante bei Raumtemperatur größer als 4.000 MΩkm ist. Ein solches Isoliermaterial hat beispielsweise die Qualität 3 GI3 nach DIN VDE 0207, Teil 20. Das Isoliermaterial ist außerdem sehr verdrückungsarm. Das ist durch eine Prüfung auf Wärmedruckbeständigkeit gemäß IEC 60811-3-1 nachgewiesen, in der es bei 150 °C (1 h Prüfzeit, k=0,6) einen Wert kleiner als 20 %, vorzugsweise kleiner als 10 %, aufweist. Verdrückungsarmut und hoher Isolationswert bewirken, daß im Vergleich zu herkömmlichen Isolierungen deutlich geringere Wandstärken für dieselben erreichbar sind.The line after Fig. 1 has two electrical wires 1 and 2, which are stranded together. Each of the two wires 1 and 2 has an electrical conductor 3 preferably made of copper and an insulation 4 surrounding it. The insulating material for the insulation 4 of the two wires 1 and 2 is a crosslinked elastomeric insulating material whose insulation resistance constant is greater than 4000 MΩkm at room temperature is. Such an insulating material has, for example, the quality 3 GI3 according to DIN VDE 0207, Part 20. The insulating material is also very low-displacement. This is evidenced by a test for heat resistance according to IEC 60811-3-1, in which it has a value of less than 20%, preferably less than 10%, at 150 ° C. (1 h test time, k = 0.6). Verdrückungsarmut and high insulation value cause significantly lower wall thicknesses for the same can be achieved compared to conventional insulation.

Die Isolationswiderstandskonstante des für die Isolierungen 4 verwendeten Isoliermaterials ist bei einer Umgebungstemperatur von 90 °C mit Vorteil größer als 15 MΩkm und vorzugsweise größer als 20 MΩkm.The insulation resistance constant of the insulating material used for the insulation 4 is advantageously greater than 15 MΩkm and preferably greater than 20 MΩkm at an ambient temperature of 90 ° C.

Die Leiter 3 der Adern 1 und 2 bestehen mit Vorteil aus Kupfer. Sie können zusätzlich auch verzinnt sein. Ihr Durchmesser kann mit Vorteil bei 1,0 mm liegen. Die Wandstärke der die Leiter 3 umgebenden Isolierungen 4 kann 0,5 mm betragen, so daß sich ein Außendurchmesser der Adern 1 und 2 von 2,0 mm ergibt.The conductors 3 of the wires 1 and 2 are advantageously made of copper. They can also be tinned. Their diameter can be advantageously 1.0 mm. The wall thickness of the conductors 3 surrounding insulation 4 may be 0.5 mm, so that there is an outer diameter of the wires 1 and 2 of 2.0 mm.

In den Zwickeln zwischen den Adern 1 und 2 liegen entsprechend dem dargestellten Ausführungsbeispiel zwei Füllelemente 5 und 6, die zusammen mit den Adern 1 und 2 verseilt sind. Der Aufbau der Füllelemente 5 und 6 ist beliebig. Sie bestehen mit Vorteil aus Isoliermaterial. Über der aus Adern 1 und 2 sowie Füllelemente 5 und 6 bestehenden Verseileinheit ist ein elektrischer Schirm 7 angeordnet, der von einer Schicht 8 aus Isoliermaterial umgeben ist. Die so fertig gestellte elektrische Leitung nach Fig. 1 hat mit Vorteil einen Außendurchmesser von 4,6 mm.In the gussets between the wires 1 and 2 are according to the illustrated embodiment, two filling elements 5 and 6, which are stranded together with the wires 1 and 2. The structure of the filling elements 5 and 6 is arbitrary. They are advantageously made of insulating material. Over the stranding unit consisting of wires 1 and 2 as well as filling elements 5 and 6, an electrical screen 7 is arranged, which is surrounded by a layer 8 of insulating material. The thus completed electric line after Fig. 1 has an advantage of an outer diameter of 4.6 mm.

Der rundum geschlossene und auf der ganzen Länge der Leitung vorhandene Schirm 7 besteht aus einem metallisierten und damit elektrisch leitfähigen Vlies auf der Basis von Polyamid. Für die Metallisierung wird mit Vorteil Kupfer eingesetzt, das aus der Dampfphase heraus auf dem Vliesmaterial abgeschieden wird. Es dringt dabei auch in das Vlies ein, so dass eine relativ dicke, bis auf Poren nahezu geschlossene, elektrisch leitende Schicht gebildet ist.The all-round closed and existing over the entire length of the line screen 7 consists of a metallized and thus electrically conductive non-woven based on polyamide. Copper is advantageously used for the metallization, which is deposited on the nonwoven material from the vapor phase. It also penetrates into the nonwoven, so that a relatively thick, almost closed to pores, electrically conductive layer is formed.

Für die den Schirm 7 umgebende Schicht 8 wird mit Vorteil ein Spinnvlies aus Polyethylenterephthalat (PETP) eingesetzt, das als Band um den Schirm 7 lückenlos herumgewickelt oder auch längseinlaufend herumgeformt sein kann. Anstelle des Spinnvlieses oder auch zusätzlich kann ein Mantel aus üblichem Isoliermaterial über dem Schirm 7 angebracht werden.For the layer 8 surrounding the screen 7, a spunbonded nonwoven made of polyethylene terephthalate (PETP) is advantageously used, which can be wrapped around the screen 7 as a band without gaps or can also be molded around in a longitudinally running manner. Instead of the spunbonded fabric or in addition, a jacket made of conventional insulating material can be applied over the screen 7.

Die Leitung nach Fig. 2 hat vier Adern 9, 10, 11 und 12, die ebenso aufgebaut sind, wie die Adern 1 und 2. Sie können allerdings andere Abmessungen als die Adern 1 und 2 haben. Neben den vier Adern ist in der Leitung nach Fig. 2 ein blanker metallischer Leiter 13 vorhanden, an dem der Schirm 7 dicht anliegt. Er dient im wesentlichen der verbesserten Kontaktierbarkeit des Schirms 7, wenn elektrische Kontaktelemente an denselben angeschlossen werden sollen, beispielsweise durch Crimpen. Die fünf Elemente 9 bis 13 sind miteinander verseilt. Sie sind mit Vorteil um ein zentrales Kernelement 14 aus Isoliermaterial herumverseilt. Das Kernelement 14 besteht vorzugsweise aus PETP-Zwirn.The line after Fig. 2 has four wires 9, 10, 11 and 12, which are the same as the wires 1 and 2. However, they may have different dimensions than the wires 1 and 2. In addition to the four veins is in the lead after Fig. 2 a bare metallic conductor 13 is present, on which the screen 7 rests tightly. It essentially serves the improved contactability of the screen 7 when electrical contact elements are to be connected to the same, for example by crimping. The five elements 9 to 13 are stranded together. They are advantageously umversilt to a central core element 14 of insulating material. The core element 14 is preferably made of PETP twisted yarn.

Der Außendurchmesser der Leitung nach den Fig. 1 oder 2 ist so klein, dass eine entsprechende Leitung beispielsweise problemlos in einem Starkstromkabel integriert werden kann. Ein solches Starkstromkabel ist schematisch im Schnitt in Fig. 3 dargestellt. Es hat drei miteinander verseilte Phasenadern 15, 16 und 17 mit herkömmlichem Aufbau, die von einem gemeinsamen Mantel 18 aus Isoliermaterial umgeben sind. Die Leitung nach der Erfindung hat so kleine Abmessungen, dass sie im dargestellten Ausführungsbeispiel im Innenzwickel zwischen den drei Phasenadern 15, 16 und 17 angeordnet werden kann. Sie ist in Fig. 3 mit 19 bezeichnet. Die Leitung 19 könnte auch an anderer Stelle im Starkstromkabel nach Fig. 3 angeordnet sein.The outer diameter of the pipe after the Fig. 1 or 2 is so small that a corresponding line, for example, can be easily integrated into a power cable. Such a power cable is schematically in section in Fig. 3 shown. It has three stranded phase conductors 15, 16 and 17 of conventional construction surrounded by a common jacket 18 of insulating material. The line according to the invention has such small dimensions that it can be arranged in the illustrated embodiment in the inner gusset between the three phase conductors 15, 16 and 17. she is in Fig. 3 denoted by 19. The line 19 could also elsewhere in the power cable after Fig. 3 be arranged.
