Claims

metallized wires are wrapped with a common textile tape and with one or more metal threads. The textile tape ensures the mechanical cohesion of the veins and the metal thread makes contact with the pressed-on lead. coat made. These metal threads are advantageously woven or drawn into the textile tape. Likewise, the common covering can also consist of a braiding made of textile and metal thread. In the manufacture of textile tapes, the metal threads are preferably located in the chain, that is to say in the longitudinal direction of the tape. The fabric can be made in any width and then cut into ribbons of the required width. The metal threads do not need to be too close to one another; they can, for example, have a distance of 10 mm from one another. If you now have the metallized wires, z. B. a three-phase cable, wrapped with such a tape, the wires are held together by the tape to form a cable core of sufficient strength and elasticity for the bends that occur. The tape can be wound up in the usual way like the paper tapes of the paper-insulated cables in a closed spiral or with an overlap, so it does not need to be laid in an open spiral like a metal tape. It does not present any obstacles for the subsequent impregnation and allows the impregnation liquid to pass through at all points on the surface. After soaking, the lead sheath is pulled directly over the tape in the known manner, and the metal threads woven into the tape now make the necessary conductive connection between the cores and the wires as a result of their contact with the metallized surfaces of the individual wires on the one hand and the inner surface of the lead jacket on the other Lead coat. A.usführungformen with the use of an ordinary textile tape are also possible, with z. B. metal threads are subsequently drawn into the finished textile tape, or the textile tape is wound in an open spiral with a metal wire or metal tape on the veins, so that the metal wire or the metal ribbon comes to rest in the free spaces of the spiral tape. Embodiments of the invention are described, for example, in FIGS. T to 3. Fig. Ι shows in cross section a cable with three metallized wires. Fig. 2 shows the top view of the cable core, with half of the lead jacket intended to be removed. Fig. 3 shows a band with three woven metal threads. In Fig. 1, 2, 3 mean the three copper 6g conductors, 4, 5, 6 the insulating sleeves, for example made of impregnated paper, the three conductors, 7, 8, 9 the metallized surfaces of the wires, 10, 11, 12 the filling material, for example jute, between the veins to achieve a round core cross-section, 14 the wrapping of the cable core according to the invention by a textile tape with woven-in metal thread and 15 the lead sheath. In Fig. 2, 15 again means the lead jacket. One sees the spiral-shaped, overlapped wrapping with the band according to the invention, the width of which is represented by 16, the overlap by 17 and which has a metal thread 18 woven into it. In Fig. 3 another form of Xessel tape is shown, which contains three woven metal threads 18. Patent-A ν Proverbs:

1. Multi-core electrical cable with cores metallized on their surface, characterized in that the wires are wrapped with a textile tape and covered by metal threads with the lead sheath Be brought into contact.

2. Multi-core electrical cable according to claim 1, characterized in that

. the common wrapping of the veins from a textile tape with woven in or drawn in metal threads.

3. Multi-core electrical cable according to claim 1, characterized in that the common wrapping of the veins consists of a textile tape in an open spiral and a metal wire, which the latter lies in the interstices of the ribbon spiral.

4. Multi-core electrical cable according to claim 1, characterized in that the common sheathing of the cores made of a unicorned layer of textile and metal threads consists.
