Description

Die Erfindung bezieht sich auf eine elektrische lnstallationsleitung, in welcher aus isolierten Leitern bestehende, der Stromführung dienende Adern zu einer Einheit zusammengefaßt sind.The invention relates to an electrical installation line, in which insulated conductors existing, the current carrying wires to a unit are summarized.

Derartige Leitungen werden in unterschiedlichsten Ausführungsformen seit vielen Jahren überall dort eingesetzt, wo elektrischer Strom benötigt wird. Die Leitungen werden in diesem Sinne in Gebäuden aller Art und auch zur Stromversorgung ortsfester und beweglicher elektrischer Maschinen eingesetzt. Gebräuchlich sind Leitungen mit drei oder mehr Adern, von denen eine in der Regel die Funktion eines isolierten Schutzleiters hat. Solange die Leitungen ausschließlich zur Stromübertragung eingesetzt werden, ergeben sich bei sachgemäßer Handhabung keine Probleme. Für eine zusätzliche Nutzung zur Übertragung nachrichtentechnischer (hochfrequenter) Signale bzw. Daten in einer heute immer weiter verbreiteten Technik sind die Leitungen nur mit Einschränkungen geeignet, da ihre lmpedanz für diesen Verwendungszweck zu ungleichmäßig ist.Such lines have been in various forms for many years used wherever electrical power is required. The lines are in this sense in buildings of all kinds and also for the power supply of stationary and movable electrical machines used. Lines with three are used or more wires, one of which usually functions as an insulated protective conductor Has. As long as the cables are used exclusively for power transmission, with proper handling there are no problems. For an additional Use for the transmission of communications (high-frequency) signals or data in a technology that is becoming increasingly widespread today, the cables are only included Restrictions suitable because their impedance is too high for this purpose is uneven.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Leitung so weiterzubilden, daß sie ohne Einschränkung auch zur störungsfreien Übertragung nachrichtentechnischer Signale geeignet ist.The invention is based, so the task described above to further train that they can also be used without interference for interference-free transmission communications signals is suitable.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • daß die Einheit aus vier zu einem Sternvierer miteinander verseilten Adern besteht,
  • daß über den Adern ein Schirm aus einer beidseitig mit Aluminium beschichteten Kunststoff-Folie angeordnet ist,
  • daß um den Schirm verzinnte Kupferdrähte mit der Funktion eines Schutzleiters herumverseilt sind und
  • daß über den verzinnten Kupferdrähten ein aus Isoliermaterial bestehender Mantel angebracht ist.
According to the invention, this object is achieved by
  • that the unit consists of four cores stranded together to form a star quad,
  • that a screen made of a plastic film coated on both sides with aluminum is arranged above the wires,
  • that tinned copper wires are stranded around the screen with the function of a protective conductor and
  • that a jacket made of insulating material is attached over the tinned copper wires.

Eine solche Leitung ist symmetrisch in Form eines Sternvierers aufgebaut. Sie hat dementsprechend eine gleichmäßige Leiturigsimpedanz von beispielsweise 100 Ohm bei 1 MHz. Hochfrequente Signale können wegen der Symmetrie der Leitung mit zwei rechtwinklig zueinander stehenden Leitungskreisen störungsfrei übertragen werden. Aufgrund der sehr gleichmäßigen Leitungsimpedanz treten auch keine wesentlichen Signalreflexionen auf. Durch den von den verzinnten Kupferdrähten - im folgenden kurz "Schutzleiter" genannt - umgebenen Schirm ergibt sich für die Leitung außerdem eine hervorragende Schirmung, und zwar auch für höhere Frequenzen im Bereich von beispielweise 1 MHz. Die Adern sind daher gegenüber einer Beeinflussung durch äußere elektromagnetische Felder geschützt und es kann auch keine Störstrahlung von der Leitung ausgehen. Durch den die Adern insgesamt umgebenden Schutzleiter erhält die Leitung außerdem eine erhöhte Sicherheit, da im Falle einer bis zum stromführenden Leiter reichenden äußeren mechanischen Beschädigung sofort eine Schutzabschaltung erfolgt.Such a line is constructed symmetrically in the form of a star quad. she has accordingly, a uniform conductor impedance of, for example, 100 ohms 1 MHz. High-frequency signals can with two because of the symmetry of the line line circuits at right angles to each other can be transmitted without interference. Due to the very uniform line impedance, there are also no significant ones Signal reflections. Because of the tinned copper wires - briefly below Called "protective conductor" - the surrounding shield also results in a cable excellent shielding, even for higher frequencies in the range of for example 1 MHz. The veins are therefore immune to external influences electromagnetic fields protected and there can also be no interference from the Line out. Due to the protective conductor surrounding the wires as a whole, the Line also increased security, because in the case of one up to the live Protective shutdown immediately reaching the outer mechanical damage he follows.

Die Leitung läßt sich dann problemlos in einem einzigen Arbeitsgang herstellen, wenn für die Verseilung der Adern und der Drähte des Schutzleiters die bekannte S/Z-Verseilung mit wechselnder Schlagrichtung der Verseilung eingesetzt wird.The line can then be easily produced in a single operation if The well-known S / Z stranding for stranding the wires and the wires of the protective conductor with changing direction of twist of the stranding.

Zur weiteren Verbesserung der Übertragungseigenschaften im nachrichtentechnischen Sinne und zur Minimierung der Abmessungen der Leitung L kann die Isolierung 2 der Adern A gemäß Fig. 2 aus zwei Schichten 6 und 7 bestehen. Für beide Schichten 6 und 7 wird in bevorzugter Ausführungsform ein vernetztes Polyolefin, beispielsweise Polyethylen, eingesetzt. Die innere, am Leiter 1 anliegende Schicht 6 ist massiv ausgeführt. Sie garantiert die für die Energieübertragung erforderliche Spannungsfestigkeit. Die äußere Schicht 7 besteht aus geschäumtem Material, so daß die Dielektrizitätskonstante der Isolierung 2 vorteilhaft herabgesetzt ist. Die äußere Schicht 7 hat zweckmäßig eine glatte Oberfläche (skin).The arrangement of the cores A in a star quad results in a symmetrical one Construction of the line L with a uniform line impedance.

Der Schirm 3 besteht aus einer Kunststoff-Folie 8, die auf beiden Seiten mit einer fest haftenden Schicht 9 bzw. 10 aus Aluminium versehen ist. Für die Kunststoff-Folie 8 wird in bevorzugter Ausführungsform ein Polyester verwendet. Sie ist beispielsweise etwa 0,13 mm dick. Die beiden Schichten 9 und 10 aus Aluminium sind jeweils mindestens 50 µm dick. Die beschichtete Kunststoff-Folie 8 ist in bevorzugter Ausführungsform längseinlaufend um die Adern A herum zu einem Rohr mit überlappenden Längskanten geformt. Die Überlappung 11 (Fig. 3) ist ausreichend breit, damit sich ein rundum geschlossener Schirm 3 ergibt. In der Überlappung 11 liegen die Aluminiumschichten 9 und 10 direkt aneinander. Die beschichtete Kunststoff-Folie 8 kann aber auch überlappend um die Adern A herumgewickelt sein. The screen 3 consists of a plastic film 8, which is fixed on both sides with a adhesive layer 9 or 10 is provided from aluminum.
