Definitions
- the invention relates to an electrical sheathed line, with an insulated copper conductor, which consists of several insulated wires, with a filling sheath arranged between the conductor insulation and the outer sheath, which also sheaths a data line.
- Such sheathed cables have a single-wire or multi-wire copper conductor.
- the multiple wires of a multi-wire copper conductor are each provided with a conductor insulation.
- the conductor insulation consists of plastic sleeves. Very often there are four cores, namely insulated wires, which are surrounded by the filler sheath, which fills the space between the outer sheath and the wire insulation, which forms a gusset due to the circular cross section of the cores.
- the outer jacket is made of polyvinyl chloride, for example.
- Such sheathed cables are manufactured in accordance with VDE 0250 for nominal voltages up to 500 volts and are suitable for laying over, on, in and under plaster in dry, damp and wet rooms, in masonry, in concrete and also outdoors if they are protected from direct sunlight .
- the laying of sheathed cables in buildings takes place less and less in masonry, especially when it comes to buildings for commercial purposes.
- the sheathed cable is increasingly being laid in cable ducts for the sake of flexibility in furnishing these rooms.
- This has the advantage that data lines to be laid can also be laid in these cable channels.
- Electrical sheathed cables of the conventional type and data lines often run side by side. This means an increased effort for the arrangement, the attachment and partly also for the connection of these lines.
- two or more cables running parallel to one another result in considerable unsightlyness if these cannot be clad.
- a sheathed cable with the features mentioned at the outset is known from EP-A-0 410 736.
- a tube is arranged in a gusset of two wires into which a ribbon-shaped optical waveguide can be introduced by means of gas transport.
- the invention has for its object to provide an electrical sheathed cable with the features mentioned so that the effort for laying, holding and connecting two pieces of line is avoided and the appearance is improved.
- This object is achieved in that the insulated copper conductor and the data line are held together with a winding, all insulated cores of the insulated copper conductor lying closely next to one another with their conductor insulation lying directly against a sheathing of the data line.
- an electrical sheathed cable insofar as it connects the energy supply e.g. is used for electrical devices, is combined with a data line.
- This integrated electrical sheathed cable can be arranged and fixed in place in a single laying step. Your appearance is accordingly handsome.
- the assembly can be manufactured in the cable plant with a small additional expenditure of material.
- the production can be produced in a work process which is uninterrupted by transport and wrapping, so that the production expenditure is reduced accordingly, which far outweighs the low additional material expenditure.
- the flexibility of the electrical sheathed cable can be achieved to the extent necessary.
- data line is to be understood to mean all electrical lines that are not primarily used for power lines, such as shielded and unshielded cables and lines for data systems, telecommunication lines, bell lines, alarm lines and fire alarm cables and the like, for which the nominal ranges in the specified voltage range lying, which is not dangerous for humans.
- power lines such as shielded and unshielded cables and lines for data systems, telecommunication lines, bell lines, alarm lines and fire alarm cables and the like, for which the nominal ranges in the specified voltage range lying, which is not dangerous for humans.
- bus lines so-called bus lines. Shielded cables should also fall under this term of the data cable.
- the electrical sheathed line is designed in such a way that the insulated copper conductor and the data line are held together with a winding.
- the wrapping ensures the cohesion of the copper conductor and the data line if the insulated copper conductor consists of several insulated wires.
- the holding together between the insulated copper conductor and the data line is particularly important in the manufacture of the electrical sheathed line.
- the wrapping ensures the relative position of the wrapped components from the processing step of the stranding to the encapsulation with the filling jacket. In addition, the wrapping but can also be used to improve the flexibility of the electrical sheathed cable.
- the electrical sheathed line is expediently designed in such a way that all of the insulated wires of the insulated copper conductor lie closely adjacent to one another with their conductor insulation lying directly against a sheathing of the data line. In this way it is achieved that the total volume to be enclosed by the outer jacket is as small as possible. Accordingly, the cost of materials for the electrical sheathed cable can be reduced.
- the wrapping is a plastic foil tape
- an optimal shape adaptation to the outer contour of the assembly can be achieved, which can be achieved from the data line and the multi-core copper conductor attached to it.
- the film strip separates the components of this assembly from the filling jacket, making it easier to remove the jacket.
- the film strip can also contribute to a small extent to electrical insulation.
- the electrical sheathed line can be developed so that the data line is arranged eccentrically to the outer sheath. This is a particularly advantageous arrangement of the largest cross section within the sheathed line in order to achieve the smallest possible outer diameter of the electrical sheathed line. Because less material needs to be used for the filling jacket in the area in which the data line is closely adjacent to the outer jacket.
- Another measure for reducing the overall cross section of the electrical sheathed cable is that the sheathing of the data line is arranged closer to the outer sheath than the insulated copper conductor. In this way, on the other hand, the filling jacket can be kept relatively thick so that the usual problem-free embedding of the insulated copper conductor is maintained.
- the invention is explained in more detail using an exemplary embodiment shown in the drawing.
- the single figure shows a cross section of an electrical sheathed cable.
- the electrical sheathed line 10 shown in the figure has an insulated copper conductor 11, which consists of three insulated wires 18.
- the conductor insulation 12 is thus the entirety of all plastic sleeves, each of which encloses a wire 19, so that the three wires 19 are insulated from one another.
- Each wire 19 is solid or multi-wire. All wires 18 are arranged close to each other so that adjacent wires touch with their plastic sheaths.
- All wires 18 of the insulated copper conductor 11 are in contact with a data line 16.
- the data line 16 consists of four data wires 20, each of which has a wire 22 surrounded by a plastic sleeve 21. All four wires are arranged or stranded around a common center in the usual way and are held together by an insulating foil tape 23. Between this film strip 23 and a casing 15 of the data line 16, a drain wire 24 is arranged as a ground connection in a manner known for installation lines for telecommunications purposes. A plastic-clad metal foil (metal side inside with contact to the drain wire 24) is arranged as a static screen in a manner not shown.
- the insulating sheaths of the wires 20 can also consist of polyvinyl chloride, as can the sheath 15.
- the data line 16 and the three wires 18 of the copper conductor 11 are held together with a wrap 17, which is, for example, a plastic tape.
- a wrap 17 which is, for example, a plastic tape. This nestles in the manner shown around the casing 15 of the data line 16 and the insulated wires 18 into the gusset formed by everyone.
- the winding 17 limits the penetration of the comparatively soft material of the filling jacket 14 into the spaces between the wires 18 and the data line 16. Accordingly, the material requirement for the filling jacket 14 is reduced and the stripping of the filling jacket is simplified when the electrical jacket line 10 is connected.
- the data line 16 is arranged eccentrically with respect to the outer jacket 13 of the electrical jacket line 10.
- Your sheath 15 is only a comparatively small distance 25 from the inner wall 26 of the outer jacket 13. Starting from this small distance 25, the cross section widens on both sides in the direction of the insulated copper conductor 11 or its wires 18.
- the wires 18 of the copper conductor 11 have from the inner wall 26 different distances. They operate within the normal range of electrical sheathed cables.
- the distance 27 is the smallest between the outer wires 18 and the inner wall 26 of the outer jacket 13.
- the distance 28 is somewhat larger for geometric reasons. Because of the sheathing 15, the data line 16 can be arranged closer to the inner wall 26 of the outer sheath 13 than the insulated copper conductor 11 or its cores 18 existing assembly and the round outer jacket 13.
Abstract
Description
Die Erfindung bezieht sich auf eine elektrische Mantelleitung, mit einem isolierten Kupferleiter, der aus mehreren isolierten Adern besteht, mit einem zwischen der Leiterisolation und dem Außenmantel angeordneten Füllmantel, der auch eine Datenleitung umhüllt.The invention relates to an electrical sheathed line, with an insulated copper conductor, which consists of several insulated wires, with a filling sheath arranged between the conductor insulation and the outer sheath, which also sheaths a data line.
Elektrische Mantelleitungen sind allgemein bekannt. Derartige Mantelleitungen haben einen eindrähtigen oder mehrdrähtigen Kupferleiter. Die mehreren Drähte eines mehrdrähtigen Kupferleiters sind jeweils für sich mit einer Leiterisolation versehen. Die Leiterisolation besteht aus Kunststoffhüllen. Sehr häufig sind vier Adern vorhanden, nämlich isolierte Drähte, die dicht nebeneinander liegend vom Füllmantel umgeben sind, der den Zwischenraum zwischen dem Außenmantel und den aufgrund des kreisförmigen Querschnitts der Adern zwickelbildenden Leiterisolation ausfüllt. Der Außenmantel besteht beispielsweise aus Polyvinylchlorid. Derartige Mantelleitungen werden nach VDE 0250 für Nennspannungen bis 500 Volt hergestellt und sind geeignet zum Verlegen über, auf, im und unter Putz in trockenen, feuchten und nassen Räumen, im Mauerwerk, in Beton und auch im Freien, wenn sie vor direkter Sonneneinstrahlung geschützt sind. Die Verlegung von Mantelleitungen in Gebäuden erfolgt immer weniger im Mauerwerk, insbesondere wenn es sich um Bauten für gewerbliche Zwecke handelt. In diesen Fällen wird die Mantelleitung aus Gründen der Flexibilität der Einrichtung dieser Räume zunehmend in Kabelkanälen verlegt. Das hat den Vorteil, daß zugleich auch zu verlegende Datenleitungen in diesen Kabelkanälen verlegt werden können. Häufig verlaufen also elektrische Mantelleitungen der herkömmlichen Art und Datenleitungen nebeneinander. Das bedeutet einen erhöhten Aufwand für die Anordnung, die Befestigung und zum Teil auch für den Anschluß dieser Leitungen. Bei Einzelverlegung auf Putz, also außerhalb eines Kabelkanals, ergibt sich durch zwei oder mehrere einander parallelgeführter Leitungen eine erhebliche Unansehnlichkeit, wenn diese nicht verkleidet werden können.Electrical sheathed cables are generally known. Such sheathed cables have a single-wire or multi-wire copper conductor. The multiple wires of a multi-wire copper conductor are each provided with a conductor insulation. The conductor insulation consists of plastic sleeves. Very often there are four cores, namely insulated wires, which are surrounded by the filler sheath, which fills the space between the outer sheath and the wire insulation, which forms a gusset due to the circular cross section of the cores. The outer jacket is made of polyvinyl chloride, for example. Such sheathed cables are manufactured in accordance with VDE 0250 for nominal voltages up to 500 volts and are suitable for laying over, on, in and under plaster in dry, damp and wet rooms, in masonry, in concrete and also outdoors if they are protected from direct sunlight . The laying of sheathed cables in buildings takes place less and less in masonry, especially when it comes to buildings for commercial purposes. In these cases, the sheathed cable is increasingly being laid in cable ducts for the sake of flexibility in furnishing these rooms. This has the advantage that data lines to be laid can also be laid in these cable channels. Electrical sheathed cables of the conventional type and data lines often run side by side. This means an increased effort for the arrangement, the attachment and partly also for the connection of these lines. For individual installation on plaster, i.e. outside of a cable duct, two or more cables running parallel to one another result in considerable unsightlyness if these cannot be clad.
Eine Mantelleitung mit den eingangs genannten Merkmalen ist aus der EP-A-0 410 736 bekannt. Es sind drei isolierte Adern vorhanden, die um ein Zentrum herum aneinander anliegend angeordnet sind. In einem Zwickel zweier Adern ist ein Rohr angeordnet, in das sich ein bandförmiger Lichtwellenleiter mittels Gastransports einbringen läßt. Infolgedessen ist der Herstellungs- und Verlegeaufwand nicht unerheblich, insbesondere bei größeren Leitungslängen, bei denen die bekannte Leitung aus kürzeren, für das Einblasen der Lichtwellenleiter geeigneten Leitungslängen mittels geeigneter Verbinder zusammengebaut werden muß.A sheathed cable with the features mentioned at the outset is known from EP-A-0 410 736. There are three insulated wires, which are arranged adjacent to each other around a center. A tube is arranged in a gusset of two wires into which a ribbon-shaped optical waveguide can be introduced by means of gas transport. As a result, the manufacturing and laying effort is not insignificant, especially in the case of longer line lengths, in which the known line must be assembled from shorter line lengths suitable for blowing in the optical waveguides by means of suitable connectors.
Der Erfindung liegt die Aufgabe zugrunde, eine elektrische Mantelleitung mit den eingangs genannten Merkmalen so auszubilden, daß der Aufwand für die Verlegung, die Halterung und den Anschluß zweier Leitungsstücke vermieden und die Ansehnlichkeit verbessert wird.The invention has for its object to provide an electrical sheathed cable with the features mentioned so that the effort for laying, holding and connecting two pieces of line is avoided and the appearance is improved.
Diese Aufgabe wird dadurch gelöst, daß der isolierte Kupferleiter und die Datenleitung mit einer Umwicklung zusammengehalten sind, wobei alle isolierten Adern des isolierten Kupferleiters dicht nebeneinander konzentriert mit ihrer Leiterisolation an einer Ummantelung der Datenleitung direkt anliegen.This object is achieved in that the insulated copper conductor and the data line are held together with a winding, all insulated cores of the insulated copper conductor lying closely next to one another with their conductor insulation lying directly against a sheathing of the data line.
Für die Erfindung ist von Bedeutung, daß eine elektrische Mantelleitung, soweit sie der Energiezuleitung z.B. zu elektrischen Geräten dient, mit einer Datenleitung zusammengefaßt wird. Es ergibt sich ein integriertes Ganzes, eine Baueinheit. Diese integrierte elektrische Mantelleitung kann in einem einzigen Verlegeschritt an Ort und Stelle angeordnet und befestigt werden. Ihr Äußeres ist dementsprechend ansehnlich. Die Baueinheit kann mit einem geringen Mehraufwand an Werkstoff im Kabelwerk hergestellt werden. Die Herstellung kann in einem durch Transporte und Umwicklungen ununterbrochenen Arbeitsprozeß hergestellt werden, so daß sich der Herstellungsaufwand entsprechend verringert, was den geringen Werkstoffmehraufwand bei weitem überwiegt. Die Biegsamkeit der elektrischen Mantelleitung kann im erforderlichen Ausmaß erreicht werden.It is important for the invention that an electrical sheathed cable, insofar as it connects the energy supply e.g. is used for electrical devices, is combined with a data line. The result is an integrated whole, a structural unit. This integrated electrical sheathed cable can be arranged and fixed in place in a single laying step. Your appearance is accordingly handsome. The assembly can be manufactured in the cable plant with a small additional expenditure of material. The production can be produced in a work process which is uninterrupted by transport and wrapping, so that the production expenditure is reduced accordingly, which far outweighs the low additional material expenditure. The flexibility of the electrical sheathed cable can be achieved to the extent necessary.
Unter dem Begriff der Datenleitung sind alle elektrischen Leitungen zu verstehen, die nicht vornehmlich der Energieleitung dienen, wie abgeschirmte und nicht abgeschirmte Kabel und Leitungen für Datenanlagen, Fernmeldeleitungen, Klingelleitungen, Alarmleitungen und Brandmeldekabel u.dgl., bei denen also die Nennspannen im benannten Spannungsbereich liegen, der für den Menschen nicht gefährlich ist. Insbesondere werden unter dem Begriff der Datenleitung sogenannte Busleitungen verstanden. Auch abgeschirmte Leitungen sollen unter diesen Begriff der Datenleitung fallen.The term data line is to be understood to mean all electrical lines that are not primarily used for power lines, such as shielded and unshielded cables and lines for data systems, telecommunication lines, bell lines, alarm lines and fire alarm cables and the like, for which the nominal ranges in the specified voltage range lying, which is not dangerous for humans. In particular, the term data line is understood to mean so-called bus lines. Shielded cables should also fall under this term of the data cable.
Die elektrische Mantelleitung ist derart ausgestaltet, daß der isolierte Kupferleiter und die Datenleitung mit einer Umwicklung zusammengehalten sind. Die Umwicklung gewährleistet den Zusammenhalt des Kupferleiters und der Datenleitung, wenn der isolierte Kupferleiter aus mehreren isolierten Adern besteht. Das Zusammenhalten zwischen dem isolierten Kupferleiter und der Datenleitung ist insbesondere bei der Herstellung der elektrischen Mantelleitung von Bedeutung. Die Umwicklung sichert die Relativlage der umwickelten Bauteile vom Verarbeitungsschritt der erfolgten Verseilung bis zum Umspritzen mit dem Füllmantel. Darüber hinaus kann die Umwicklung aber auch dazu herangezogen werden, um die Flexibilität der elektrischen Mantelleitung zu verbessern.The electrical sheathed line is designed in such a way that the insulated copper conductor and the data line are held together with a winding. The wrapping ensures the cohesion of the copper conductor and the data line if the insulated copper conductor consists of several insulated wires. The holding together between the insulated copper conductor and the data line is particularly important in the manufacture of the electrical sheathed line. The wrapping ensures the relative position of the wrapped components from the processing step of the stranding to the encapsulation with the filling jacket. In addition, the wrapping but can also be used to improve the flexibility of the electrical sheathed cable.
Die elektrische Mantelleitung wird zweckmäßigerweise so ausgestaltet, daß alle isolierten Adern des isolierten Kupferleiters dicht nebeneinander konzentriert mit ihrer Leiterisolation an einer Ummantelung der Datenleitung direkt anliegen. Auf diese Weise wird erreicht, daß das insgesamt vom Außenmantel einzuschließende Volumen möglichst gering wird. Dementsprechend kann der Werkstoffaufwand für die elektrische Mantelleitung reduziert werden.The electrical sheathed line is expediently designed in such a way that all of the insulated wires of the insulated copper conductor lie closely adjacent to one another with their conductor insulation lying directly against a sheathing of the data line. In this way it is achieved that the total volume to be enclosed by the outer jacket is as small as possible. Accordingly, the cost of materials for the electrical sheathed cable can be reduced.
Wenn die Umwicklung ein Folienband aus Kunststoff ist, kann eine optimale Formanpassung an die Außenkontur derjenigen Baugruppe erreicht werden, die aus der Datenleitung und dem daran anliegenden mehradrigen Kupferleiter erreicht werden. Das Folienband trennt die Bestandteile dieser Baugruppe vom Füllmantel und erleichtert so die Abmantelung. Letztlich kann das Folienband in geringem Umfang auch zur elektrischen Isolierung beitragen.If the wrapping is a plastic foil tape, an optimal shape adaptation to the outer contour of the assembly can be achieved, which can be achieved from the data line and the multi-core copper conductor attached to it. The film strip separates the components of this assembly from the filling jacket, making it easier to remove the jacket. Ultimately, the film strip can also contribute to a small extent to electrical insulation.
Die elektrische Mantelleitung kann so weitergebildet werden, daß die Datenleitung exzentrisch zum Außenmantel angeordnet ist. Es ist dies eine besonders vorteilhafte Anordnung des größten Querschnitts innerhalb der Mantelleitung, um zu einem möglichst kleinen Außendurchmesser der elektrischen Mantelleitung zu gelangen. Denn es braucht weniger Werkstoff für den Füllmantel in demjenigen Bereich aufgewendet zu werden, in dem die Datenleitung dem Außenmantel dicht benachbart ist.The electrical sheathed line can be developed so that the data line is arranged eccentrically to the outer sheath. This is a particularly advantageous arrangement of the largest cross section within the sheathed line in order to achieve the smallest possible outer diameter of the electrical sheathed line. Because less material needs to be used for the filling jacket in the area in which the data line is closely adjacent to the outer jacket.
Eine weitere Maßnahme zur Reduzierung des Gesamtquerschnitts der elektrische Mantelleitung liegt darin, daß die Ummantelung der Datenleitung dichter am Außenmantel angeordnet ist, als der isolierte Kupferleiter. Hierdurch kann der Füllmantel andererseits noch relativ so dick gehalten werden, daß die übliche problemlose Einbettung des isolierten Kupferleiters gewahrt bleibt.Another measure for reducing the overall cross section of the electrical sheathed cable is that the sheathing of the data line is arranged closer to the outer sheath than the insulated copper conductor. In this way, on the other hand, the filling jacket can be kept relatively thick so that the usual problem-free embedding of the insulated copper conductor is maintained.
Die Erfindung wird anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die einzige Figur zeigt einen Querschnitt einer elektrischen Mantelleitung.The invention is explained in more detail using an exemplary embodiment shown in the drawing. The single figure shows a cross section of an electrical sheathed cable.
Die in der Figur dargestellte elektrische Mantelleitung 10 hat einen isolierten Kupferleiter 11, der aus drei isolierten Adern 18 besteht. Die Leiterisolation 12 ist also die Gesamtheit aller Kunststoffhüllen, die jeweils einen Draht 19 umkleiden, so daß die drei Drähte 19 untereinander isoliert sind. Jeder Draht 19 ist massiv oder mehrdrähtig. Alle Adern 18 sind dicht nebeneinander angeordnet, so daß sich einander benachbarte Adern mit ihren Kunststoffhüllen berühren.The electrical
Alle Adern 18 des isolierten Kupferleiters 11 liegen an einer Datenleitung 16 an. Die Datenleitung 16 besteht aus vier Datenadern 20, die jeweils von einer Kunststoffhülle 21 umgebenen Draht 22 aufweisen. Alle vier Adern werden in üblicher Weise um ein gemeinsames Zentrum angeordnet bzw. verseilt und sind von einem isolierenden Folienband 23 zusammengehalten. Zwischen diesem Folienband 23 und einer Ummantelung 15 der Datenleitung 16 ist in bei Installationsleitungen für Fernmeldezwecke bekannter Weise ein Beidraht 24 als Erdungsanschluß angeordnet. Darüber ist eine kunststoffkaschierte Metallfolie (Metallseite innen mit Kontakt zum Beidraht 24) als statischer Schirm in nicht dargestellter Weise angeordnet. Die Isolierhüllen der Adern 20 können ebenso aus Polyvinylchlorid bestehen, wie die Ummantelung 15.All
Die Datenleitung 16 und die drei Adern 18 des Kupferleiters 11 werden mit einer Umwicklung 17 zusammengehalten, die beispielsweise ein aus Kunststoff bestehendes Folienband ist. Dieses schmiegt sich in der dargestellten Weise um die Ummantelung 15 der Datenleitung 16 und die isolierten Adern 18 herum in die von allen gebildeten Zwickel hinein. Die Umwicklung 17 begrenzt das Eindringen des vergleichsweise weichen Werkstoffs des Füllmantels 14 in die Zwischenräume zwischen den Adern 18 und der Datenleitung 16. Dementsprechend wird der Werkstoffbedarf für den Füllmantel 14 reduziert und das Abisolieren des Füllmantels im Anschlußfall der elektrischen Mantelleitung 10 vereinfacht.The
Aus der Darstellung ist ersichtlich, daß die Datenleitung 16 in Bezug auf den Außenmantel 13 der elektrischen Mantelleitung 10 exzentrisch angeordnet ist. Ihre Ummantelung 15 hat nur einen vergleichsweise geringen Abstand 25 von der Innenwand 26 des Außenmantels 13. Von diesem geringen Abstand 25 ausgehend erweitert sich der Querschnitt beidseitig in Richtung auf den isolierten Kupferleiter 11 bzw. dessen Adern 18. Die Adern 18 des Kupferleiters 11 haben von der Innenwand 26 unterschiedliche Abstände. Sie bewegen sich im Rahmen des bei elektrischen Mantelleitungen üblichen. Am geringsten ist der Abstand 27 zwischen den außenliegenden Adern 18 und der Innenwand 26 des Außenmantels 13. Der Abstand 28 ist aus geometrischen Gründen etwas größer. Wegen der Ummantelung 15 kann die Datenleitung 16 dichter an der Innenwand 26 des Aussenmantels 13 angeordnet werden, als der isolierte Kupferleiter 11 bzw. dessen Adern 18. Demgemäß dient der Füllmantel 14 zum Ausgleich der unsymmetrischen mittleren, aus der Datenleitung 16 und dem isolierten Kupferleiter 11 bestehenden Baugruppe und dem runden Außenmantel 13.It can be seen from the illustration that the
