Abstract (en)

[origin: WO2007039302A1] The invention relates to a slip ring consisting of a substrate material and a sliding contact surface made of gold or a gold alloy, the sliding contact surface being stabilised by a support base, and to the use of a slip ring in slip ring transmitters (in particular in wind power plants or industrial robots), for transmitting control signals and control currents and generator currents.An extended service life, in conjunction with improved quality, a reduced drop in voltage and considerable savings in the amount of gold used can be achieved with the invention.
