Abstract:
1. A hybrid cable for electrical drives, comprising at least one signal line; power lines for supplying a drive with electrical power; at least one additional line; an inner electrical shield in which said signal line configured as an electrical line is enclosed, said power line and said at least one additional line being located on a periphery of said inner electrical shield; an outer electrical shield which encloses said power line and said additional line; and at least two shield wires located between said outer shield and said inner shield thereby resulting in improved shielding and mechanical separation between said power lines and said additional lines, wherein the shieldwires are dimensioned to essentially fill an entire radial intermediate space between the inner shield and the outer shield to ensure said mechanical separation between said power lines and said additional lines, wherein the shieldwires are configured such that cross sections of the shieldwires are increased while insulation thickness of the shieldwires are reduced, whereby the shielding is improved based on an increased copper space factor.
