Applications

Wind turbines are installed in regions exposed to climatic conditions that are severe and especially constraining for the system consisting of the slip ring assembly, brushes, and brush holders.

In a break from the conventional technology using a slip ring assembly with bronze or steel rings, CARBONE LORRAINE has developed an innovative solution using carbon rings.

A wind turbine operates for long periods in variable conditions:

almost zero current,
many different speeds of rotation,
load current rarely constant,
corrosive environments, both wet and dry,
strong vibrations.

Reducing the weight is a permanent concern.

CARBONE LORRAINE has perfectly characterised and modelled, in the laboratory, the operation of wind turbines, and this has enabled us to optimise the development of the new products we propose today.
