Definitions
- the invention relates to a self-supporting electrical line according to the preamble of claim 1.
- Self-supporting elevator lines such as B. Construction site lift lines are used for hanging lengths up to 400 Meters used. To one for catching the weight of such long cable lengths to sufficient tensile strength ensure the known self-supporting electrical Cables a high tensile and low-stretch support element on, however, a correspondingly high rigidity owns. When the elevator is in operation, the one that is not required must be used Length of the electrical line, which is determined by the respective height of the Car is determined, in some way as possible be stored in a confined space without the electrical wiring thereby being damaged.
- DE-16 40 773A describes a process for the production stretchable helical electric spiral Lines known, which stranded together from several or stranded insulated wires, where instead of one Core or an additional dummy wire can be provided, where the dummy wire generates part of the spring force. From the stranded veins and a sheath The line is wound on a mandrel, in the wound state warmed, cooled and unwound. Before or when winding up the mandrel is twisted. This well-known line will primarily as a connecting line between a telephone and used a telephone handset.
- the invention is based on the problem of a self-supporting electrical line, which has a central support member, so train that they are easily stored in a confined space can be.
- the advantages that can be achieved by the invention exist especially in that the self-supporting electrical line due to the pre-twist or the embossed Tension even in long lengths in a confined space can be stored in a pot. This is particularly so of great advantage in elevator lines, in which the through the respective height of the car certain excess length of the electrical line must be stored.
- One pre-spin having self-supporting electrical line is above also particularly simple by the inventive method and inexpensive to manufacture. For a particularly reliable It is storage of the electrical line in a receptacle advantageous if the line for vulcanization or Networking is wound up as tightly as possible.
- At least one the electrical conductor from stranded together or strangled steel and copper wires is formed.
- the coat is made of a rubber elastic Material is formed so that the self-supporting electrical Head a good flexibility and has high abrasion resistance.
- Embodiments of the invention are in the drawing shown in simplified form and in the following Description explained in more detail.
- 1 shows a Embodiment of an inventive self-supporting electrical line
- Fig. 2 the Storage of such a self-supporting electrical line in a storage pot
- Fig. 3 a Process step for producing the self-supporting electrical wire.
- Construction site line usable self-supporting electrical line 1 has a central support member 3, the for example from a drain 5 made of an ethylene-propylene rubber and applied to the inlay 5 high tensile elements 7 is formed. Both high tensile elements 7 it can be z.
- Support member 3 are in the illustrated Embodiment four energy wires 9 and one Control core bundle 11 stranded.
- Each of the four energy veins 9 has one of an electrical insulation 13 enclosed electrical conductor 15 for Energy transfer on.
- the control wire bundle 11 has one for example a core 17 formed from a hemp cord, around the z. B.
- An inner jacket 23 is above it provided that the gusset between the energy wires 9, the control wire bundle 11 and the support member 3 fills.
- the Inner jacket 23 is enclosed by an outer jacket 25, which, for example, is made of the same as the inner jacket 23 a rubber-elastic material is formed.
- Outer jacket 25 are shown in the Embodiment to increase the tensile strength of the Outer jacket tensile threads 27 z. B. in the form of a Braid integrated.
- the electrical conductors 15 for example, from one another stranded or twisted steel and copper wires educated.
- the electrical conductor 21 of the Control cores 12 can be twisted together or tangled steel and copper wires exist.
- the Outer jacket 25 is applied, as in FIG. 3 shown as an example on a narrow coil 29, for example wound on a tight steel spool.
- the Coil 29 with the wound self-supporting electrical line 1 is placed in a furnace 31.
- the outer jacket 25 is the self-supporting electrical line 1 in the wound state of Pipe vulcanized or cross-linked by heating.
- FIG. 2 shows an example of how a Excess length of an electrical one serving as an elevator line Line 1 is stored in a narrow pot 33.
- the arrow 34 indicates the movement of the self-supporting electrical line 1 in the process of a car, not shown, of the elevator.
- the Pre-spin of the self-supporting according to the invention electrical line 1 ensures that this at Lowering the car reliably and safely in the narrow pot 33 approximately in the form of a spiral discards. This is additionally shaped by a funnel Insertion section 35 at the upper end of the receptacle 33 facilitated. It is for easy and safe Storage of line 1 is advantageous if the diameter the core of the coil 29 on which the self-supporting electrical line 1 during vulcanization or Networking is wound up, is smaller than the inner one Diameter of the pot 33.
