Mersen offers a wide range of carbographitic and bakelite-graphite brushes for FHP motors. 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 (15 to 55m/s) Brush wear indicator systems Carbographitic grades are prepared from carbon and coke powders (natural or artificial) agglomerated with appropriate binders to give them good resistance to high temperature and variable loads. Bakelite-graphite grades are made from natural or artificial graphite powders agglomerated with a thermo-hardening resin to give them a high electrical and mechanical resistance power.
