Abstract:
1. Electrical conductor comprising: a central core; at least two layers, which are arranged above the core composed of electrically conductive individual wires, which are twisted around the core in a first layer and around the first layer in a second layer, in which the individual wires of the first layer are steel wires with an ultimate tensile strength of more than 800 N/mm a wire composed of a soft-annealed copper with an ultimate tensile strength of at least 210 N/mm the ultimate tensile strength of the steel wires is between 800 N/mm the ultimate tensile strength of the copper wires is between 250 N/mm the lay length of the copper wires is between 8×D and 18×D where D is the diameter of the conductor over the second layer.
