Power and signal transmission carbon brush

for wind turbine

Graphite brushes for current and signal transmission: pitch motors, annealers, galvanic lines, motor driven cable reels... Graphite brushes for current and signal transmission Mersen offers a wide range of metal graphite brushes for current and signal transmission. Power transmission groups applications of Mersen's carbon brushes where a current shall be passed between two elements in rotation with respect to each other: annealers, electrolytic treatment lines, Ward Leonard groups, etc. Metal-graphite grades are prepared from purified natural graphite and metal powders (copper, silver…); then they are pressed and baked to bring them to the required solidity and cohesion levels. Mersen also supplies carbon brushes for transmitting signals, such as data collection from a production line, command signals for a robot or the windmill pitch motor, etc. Main features • Selected materials • Specific machined or pressed to size designs • High quality tamping • Good mechanical stability • High electrical conductivity • Low friction coefficient • High transient current density • Wide speed range (0 to 40m/s) Applications • Wind mills (pitch motors, yaw motors) • Metallurgy (annealers, electrolytic treatment lines, finishers) • Packaging • Elevators • Fairground rides • Ships (pods) • Machine tools • Blowers and fans • Extractors • Water treatment • Military (radars, tank gun turrets...)
