1. An electrical connector for electrically connecting a rotor of an electric generator to a slip ring, the electrical connector comprising:
a first support cartridge, the first support cartridge being electrically isolated,
at least a second support cartridge distanced from the first support cartridge along a longitudinal axis of the electrical connector, the second support cartridge being electrically isolated,
at least one conductive bar extending along the longitudinal axis, the at least one conductive bar being fixed to the first support cartridge and the second support cartridge, and
a winding connector for electrically connecting the at least one conductive bar to a rotor winding of the rotor,
wherein the electrical connector comprises a hollow housing, and wherein the electrical connector comprises an insulating filler provided between the hollow housing and the at least one conductive bar, and
wherein the electrical connector is configured to be housed within an axial cavity of a rotor shaft of the rotor.
