634 carbon brush has a resistivity of 18, flexural strength of 5.2, Shore hardness of 20, bulk density of 1.28, contact voltage drop of 2.50, friction coefficient of 0.29, rated current density of 10, and allowable circumferential speed of 81m/s. NCC634 carbon brush has excellent collecting performance and is suitable for Slip ring of steam turbine generator.

 

 

634 carbon brush has a long service life and does not wear the commutator or Slip ring. The carbon brush has good commutation and current collection performance, which suppresses sparks within the allowable range and reduces energy loss. The carbon brush operates without overheating, with low noise, reliable assembly, and no damage.
