Definitions

  • the invention relates to an electrical sheathed cable, with an insulated copper conductor, and with a filling sheath arranged between the conductor insulation and the outer sheath.
  • An electrical sheathed cable with the aforementioned features is 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.
  • the sheathed cable is increasingly being laid in cable ducts for the sake of flexibility in furnishing these rooms.
  • The 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.
  • the invention is therefore based on the object of designing an electrical sheathed cable with the features mentioned at the outset in such a way that the effort for laying, holding and connecting two lines is avoided and the appearance is improved.
  • the filling sheath also sheaths a sheathed data line which lies directly on the conductor insulation.
  • 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 structural unit can be manufactured in the cable plant with a small amount of additional 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 understood to mean all electrical lines that are not primarily used for power transmission, such as shielded and unshielded Cables and lines for data systems, telecommunication lines, bell lines, alarm lines and fire alarm cables and the like, in which the nominal ranges are within the specified voltage range, which is not dangerous for humans.
  • data line is understood to mean so-called bus lines. Shielded cables should also fall under this term of the data cable.
  • the electrical sheathed line can be designed in such a way that the insulated copper conductor and the data line are held together with a winding.
  • the winding ensures the cohesion of the copper conductor and the data line, especially in the event that 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 can also be used to improve the flexibility of the electrical sheathed cable.
  • 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 possibly 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.
  • the electrical sheathed line is expediently designed in such a way that a plurality of insulated wires of the insulated copper conductor adjoin the sheathing of the data line in close concentration. 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 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 enough to ensure that the insulated copper conductor is embedded without any problems.
  • 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.
  • 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. Accordingly, the filling sheath 14 serves to compensate for the asymmetrical middle ones, consisting of the data line 16 and the insulated copper conductor 11 existing assembly and the round outer jacket 13.
