Abstract
An electrooptical communications and power cable has at least one light waveguide, which is arranged in a central multifibre bundle consisting of a smooth flexible metal tube and provided with a primary jacket. Two layers of stranded metal wires are extended coaxially to the multifibre bundle. The metal wires are also used for relieving a traction and/or transversal load. The internal metal wire layer consists of metal wires exhibiting a good electric conductivity. The external metal wire layer has metal wires which are arranged alternately individually and/or group groupwisely and exhibit a good electrical conductivity and metal wires exhibiting a high traction strength. The two wire layers are held at a distance (a) from each other by an insulating layer. The communications and power cable is used first of all for an electrooptical power connection between two voltage converters in an intelligent system.

- 12. An electrooptical communications and power cable, which comprises, in a central bundle core comprising a smooth, flexible metal tube, at least one optical waveguide with a primary sheathing, two layers running coaxially with respect to the bundle core and comprising stranded metal wires, which are also used as relief from tensile and/or transverse forces, and an outer sheath, said two layers including an inner wire layer comprising electrically highly conductive metal wires, and an outer wire layer comprising first metal wires arranged in alternating fashion individually and/or in groups and having a high electrical conductivity, on the one hand, and second metal wires having a high tensile strength, on the other hand, held at a distance (a) by means of an insulating layer.
