Fl 4903 20.08.91 ABSTRACT OF THE DISCLOSURE The electro-optical overhead cable is made up of round stranding elements as follows: a) Around the core element are stranded at least one layer of wires mainly of high tensile strength, and thereover at least one layer of wires mainly of electrical conducting, b) the core element consists of a steel wire with about 2.5 mm in diameter or of a massiv element of a high tensile strength plastic material with about 5 mm in diameter, and c) in the first wire layer around the core, at least two wires are replaced each by a high-grade steel tube with an outer diameter of about 2.5 mm containing at least 12 light wave guides (LWG). (These constructions are laid down in the claims 1 to 3 and Fig. 1 and 3.) Alternatively or in addition, the electro-optical cable is made up of a core and at least two wire layers surrounding the core, while the core consists of a high- grade steel tube with 5 mm in diameter containing 12, 18 or 24 bundles of LWG, with 2 LWG in each bundle. (This construction is laid down in claim 4 and Fig. 2.) Also it is possible to combine the cable construction shown in Fig. 2 with that of Fig. 3 (claims 5 and 6).
