We are using CARBONE LORRAINE made carbon brushes for the last 13 years and as such have not faced any major problem or issues related to the quality of these brushes. We are using these brushes on our 323 MWatt turbo generators at a rotational speed of 3000rpm. The performance of these brushes in terms of these parameters have been found satisfactory. 1.Low friction coefficient, 2.Good current distribution, 3.Minimum electrical losses, 4.Less impact on slip rings, 5.Good life time. I hope manufacturer of these brushes will maintain or further improve upon these standards in future. Irfan Ahmed, Senior Electrical Engineer, International Power Global Development Ltd
