Abstract
The invention relates to an electrical conductor which is made up substantially of one or even several metal conductors which are sheathed by a graphene layer. Particularly in the case of the electrical conductor transporting an alternating current, the current in the conductor is forced radially outwards and therefore flows in the graphene layer. Since graphene has a substantially better conductivity than the materials customary in this application, such as copper for example, relatively low losses are accordingly produced and substantially higher degrees of efficiency can be achieved. The electrical conductor constructed in this way is used in a stator and/or rotor winding of an electrical machine, so that it has a significantly elevated power-to-weight ratio.
