Description

[0020] Further expedient embodiments and advantages of the invention from the subject matter of the following description of illustrative embodiments of the invention with reference to the figures of the drawing, wherein identical reference signs refer to components that act in the same way, and wherein

[0021] FIG. 1 illustrates an illustrative embodiment of the cable holder according to the invention in a perspective view,

[0022] FIG. 2 illustrates two cable holders, accommodated in a container, in accordance with one illustrative embodiment of the invention, and

[0023] FIG. 3 illustrates two further illustrative embodiments of the cable holder according to the invention, including a termination holder within a container.

[0024] FIG. 1 shows an illustrative embodiment of a cable holder 1 according to the invention, in accordance with the present invention. The cable holder 1 has a holding frame 2, a cable reel with a winding cylinder 3 and two side limits 4, which are arranged on both sides of the winding cylinder 3 and are connected firmly thereto. A high-voltage cable 5 is wound onto the winding cylinder 3. The holding frame 2 has a base 6 as well as a holding support 7 and two transverse reinforcements 8, which each extend between one corner of the base 6 and the holding support 7. The holding support 7 projects perpendicularly from the base 6 on one side of the latter in a central position. A rotary bearing 9 is arranged at its end remote from the base 6. The side limits 4, which are connected firmly to the hollow winding cylinder 3 of circular-cylindrical design, have a bearing pin, not illustrated in the figures, which engages in the rotary bearing 9 of the respective holding support and is held there in a rotatable manner by a ball bearing. In this way, the cable reel 3, 4 is rotatably mounted in the holding frame 2.

[0025] FIG. 2 shows two cable holders 1 according to FIG. 1, which are arranged within a 20 foot container 10. The interior of the 20 foot container has a width of 2352 mm and a height of 2690 mm. It is evident that the cable holders 1 are of smaller configuration than these dimensions, wherein two apertures 11, which enable a prong of a forklift truck to be inserted, can be seen in the base 6 of each holding frame 2. With the aid of the forklift truck, the cable holders 1 can easily be inserted into the 20 foot container and removed therefrom.

[0026] FIG. 3 shows a further illustrative embodiment of a cable holder 1 according to the invention. For this purpose, two cable holders 1 are placed in a 20 foot container 10. In this illustration, it is evident that each cable holder 1 has a terminal holder 12. The terminal holder 12 is firmly connected to a side wall of the container 10 and is used for the horizontal mounting of a cable termination 13 with solid insulation, which terminates the high-voltage cable 5 at one of the ends thereof. The cable termination 10 has an outdoor terminal 14, which projects at the free end from an insulator 15 of conical configuration and is provided for connection to an air-insulated high-voltage line. An internal conductor (not illustrated in the figures) connected in an electrically conducting fashion to the outdoor terminal 14 extends through the insulator 15. To avoid leakage currents, the insulator 15 is provided with ribs on the outside. The internal conductor of the insulator 15 is, in turn, connected to the internal conductor of the high-voltage cable 5, which is wound onto the cable reel 3, 4 of each cable holder 1.

[0027] To avoid having to impart rotation to the cable reel 3, 4 manually, a pneumatic drive device 16 that is connected in a fixed manner to the holding frame 2 is provided. The pneumatic drive device 16 can be connected to the compressed air system of a heavy goods vehicle, making the drive device 16 independent of the respective power supply available on site.

[0028] The cable reel 3, 4 of the cable holders 1 shown in FIGS. 1 to 3 has a horizontal axis of rotation, wherein the inside diameter of the circular-cylindrical winding cylinder 3 is 1500 mm. The high-voltage cable 5 can therefore also be held by the cable holder 1 even over long periods of time without the high-voltage cable 5 having to be unwound from the cable reel 3, 4 at fixed intervals. In this case, the cable holder 1 is of such compact design that storage of the cable holder 1 within a standardized 20 foot container is made possible. In this way, low-cost storage over long periods of time is made possible, while the container 10 with the cable holder 1 can be transported quickly to the desired destination when required.
