USED IN PAPER AND CEMENT PLANTS Mersen offers a wide range of metal graphite brushes, particularly adapted to asynchronous motors with wound rotor. Metal graphite brushes grades are prepared from purified natural graphite and metal powders (copper, silver…); then they are compressed and baked to bring them to the required solidity and cohesion levels. Characteristics: Specific designs Selected materials High quality tamping Optimized cable dimensions Good mechanical stability High electrical conductivity Low friction coefficient High transient current density Wide speed range (15m to 55m/s) Brush wear indicator systems"
