The carbon brush size 25.4*38.1*102mm is specially made for steam turbine generators of 300MW, 330MW, 600MW, 660MW capacity. Its function is to reliably contact the generator slip ring and transmit the rotor excitation current. It is mainly applicable to the slip ring of high-speed turbo generator and has been widely used in many large thermal power plants. As a consumable element that needs to be replaced constantly in the steam turbine generator, the carbon brush has always been an important link in the maintenance of the generator. Good carbon brushes can effectively reduce the maintenance cost of the generator.
