Definitions

  • the invention relates to a flexible electrical power line consisting of a central core, energy cores stranded around the core and at least one also around the core stranded control line, in which the energy wires have a flexible electrical conductor with insulation and braid over it Shield formed from metallic wires are attached (DE-U-296 13 870).
  • Such power lines are used, for example, for energy supply portable consumers are used, who go back and forth in predetermined ways be moved. Such consumers are, for example, motors from Transport trolleys, tool slides or cranes.
  • the power lines are too can be used when an easily manufactured, flexible connection to consumers a voltage source is required, which should also be easy to dismantle.
  • On A special application is the power supply of those in the waiting position Aircraft that supply energy from the tarmac when the engines are switched off become.
  • the control line contained in the power lines can be used for transmission of control signals are used by which the corresponding devices embossed functions can be activated.
  • the core of the control line consisting of several electrically insulated conductors arranged. This allows a control line with a larger number of conductors mechanically well protected in the cross section of the power line.
  • the control line can be made from a braid Be surrounded by copper wires. There is also no information about its structure made as about the braid surrounding the energy veins as a shield.
  • the invention has for its object the power line described above while maintaining their good flexibility so that they can be used even at higher levels Frequencies does not bother.
  • this power line can also be used Data are transmitted, for example measurement data.
  • the intended one Data line is surrounded by a braid with a very high optical coverage, so that interference with data transmission due to radio frequency fields or energy can be largely excluded.
  • Using higher frequencies in the order of 400 Hz mentioned can be for example the torque of connected to the power line better control electric motors.
  • the energy veins themselves from are surrounded by a mesh with a very high optical coverage, so that too interference radiation emanating from the same can be largely excluded can.
  • Fig. 1 shows a cross section through a power line according to the invention.
  • Fig. 2 to 5 details of the power line in enlarged views.
  • the heavy current line shown in cross section in FIG. 1 is used, for example, for Energy supply and for the control and monitoring of a transport trolley for a blast furnace. In addition to the necessary electrical properties for this Use also requires resistance at higher temperatures.
  • the power line has four energy wires 1 and two control lines 2, all of them are stranded around a central core 3. At least one control line 2 to be available. In the between the energy wires 1 and the control lines 2 remaining outer gussets are five data lines 4 and one for example an ethylene-propylene terpolymer (EPDM) existing filling element 5 arranged. If there are fewer than five data lines 4, one becomes corresponding larger number of filling elements 5 used.
  • the energy wires 1, control lines 2, data lines 4 and filling element 5 existing line core is from one Surround inner jacket 6. Over the inner jacket 6 are one as a torsion protection serving, for example consisting of a cord 7 and a Outer jacket 8 attached.
  • the individual wires of the conductor 9 and the metal wires of the braid 11 are preferably made of copper.
  • the braid 11 has a flat pitch angle that lies between 50 ° and 60 °, molded around the insulated conductor 9. This results in a linear coverage of over 60%, which corresponds to an optical coverage of over 80%.
  • the corresponding Energy core 1 is therefore very flexible and also at frequencies of the order of magnitude of 400 Hz electrically almost tight.
  • the Pitch 11 of the braid 11 at 53 °. This results in an optical coverage of 85%.
  • control lines 2 have six wires insulated, for example, with EPDM 12, which is stranded around a support member 13 surrounded by an EPDM layer are.
  • the external dimensions of the control lines 2 advantageously correspond to the External dimensions of the energy wires 1.
  • the core 3 has a central tension element 14, which is surrounded by an envelope 15 is surrounded.
  • the casing 15 consists of a cross-linkable or vulcanizable Material such as rubber. It is networked in the finished power line.
  • the Envelope 15 has indentations 16 over the entire axial length of the core 3 provided that the contour of the respective lying in one of the indentations 16 Energy core 1 corresponds.
  • the tension element 14 consists, for example, of one of Glass thread surrounded by aramid threads.
  • the data lines 4 have four wires 17, twisted together which a shielding braid 18 and a jacket 19 are attached.
  • the wires 17 are conventional wires known from telecommunications with one for example insulation made of polyethylene.
  • the jacket 19 is made for example from EPDM.
  • the braid 18 has a flat pitch angle applied, which is between 50 ° and 60 °. It has an optical coverage of at least 85%. In a preferred embodiment, the pitch angle of the Braid 18 at 54 °. The optical coverage is then 90%.
  • the inner jacket 6 consists of crosslinkable or vulcanizable material, such as for example a polychloroprene mixture.
  • the braiding 7 is an open braid executed. It is integrated in the outer jacket 8, which is also made of a polychloroprene mixture can exist.
  • the power line according to the invention is manufactured, for example, as follows:
