1. An electrical machine having a winding support having multiple grooves, which carries at least one winding, wherein the winding is formed by a conductor which has multiple groove sections which each extend within one of the grooves of the winding support and which are conductively connected by connecting sections of the conductor which are outside the grooves, wherein the winding comprises multiple conductor clamps which are conductively connected to one another and which each form two groove sections and a coupling section connecting the groove sections, wherein the individual conductor clamps are inclined with respect to the radius of the winding support in such a way that a first free end of the respective conductor clamp lies in a lower winding level than a second free end of the conductor clamp, wherein the conductor has an insulation layer applied to the conductor at least individually on each one of the groove sections, wherein the insulation layer has layer thicknesses different from one another for at least two of the groove sections within a same one of the grooves of the winding support, wherein both groove sections of a first of the conductor clamps have an insulation layer having a first layer thickness and wherein both groove sections of a second of the conductor clamps have an insulation layer having a second layer thickness different from the first layer thickness.
