turbogenerator carbon brush / for generators and alternators

Mersen offers a wide range of carbon brushes for generators and alternators.

? For turbogenerators, our LFC brush grades are internationally renowned, especially LFC 554 grades.

These soft graphite grades are prepared from graphite powders (natural purified or artificial) agglomerated with appropriate binders to give them good resistance to shocks and mechanical vibrations.

The advantages of the LFC554 grade are mainly related to its specific formulation and production process, producing a grade of light weight, high strength and high performance for optimum energy efficiency:
?
Excellent damping and lubricating capabilities?
- Extended carbon brush life time (low wear)?
- Respect of the slip rings over time?
- Very low and stable friction coefficient?
- Excellent mechanical stability up to 100 m/s (328 ft/s)?
- Limited ghosting

Very low electrical resistance
- Cooler running
- Homogeneous current distribution in the carbon brushes
- Current density range: 7 to 13 A/cm? (45 to 84 A/in?)
- Low and stable voltage drop
