CARBONE LORRAINE carbon brushes have proven performance on both high-speed turbines and water wheel generators. For high-speed steam turbines (3,600RPM), grade LFC554 provides unequalled performance on all makes of equipment - General Electric, Westinghouse, GEC, ABB etc. The outstanding qualities of this grade are minimal degree of selective action and long brush life.

For water wheel generators, CARBONE LORRAINE brushes have been successfully used globally for many years on all makes of equipment. Grades WA10 and WL10 are the Westinghouse approved standards and grade L1 for General Electric. For silicone insulated units grade M44A provides excellent life and performance.


WIND POWER GENERATION

More and more countries are turning to renewable power sources for the future and the market is rapidly expanding. Groupe CARBONE LORRAINE, following our on-going strategy and commitment to protection of the environment, has been involved with Wind Power projects for quite a few years. We have developed innovative products for this industry. Graphite materials such as M8295 have been developed to extend brush life, improve friction properties, stability, current distribution and to function under severe conditions including salty atmospheres. In order to provide a package solution, Groupe CARBONE LORRAINE was also invested substantially in developing Slip-Ring assemblies using carbon or Bronze rings as well as holders at Pressure Systems. Using graphite as the ring material, the benefits are:

· Net weight of the slip ring can be reduced. · Corrosion free · Life · Excellent no load and very low current operation · High peripheral speeds · Low operating cost.
