Bronze-ring slip ring assemblies:

We have developed a specially treated electrographite grade for longer life.
This grade has very good friction, stability, and current distribution properties.
It is an excellent response to the constraints of the wind turbine application.

Carbon slip ring assemblies:

The Carbon slip ring assembly is the solution to put forward for the wind turbine application:

lower weight
no corrosion of the carbon,
outstanding life (brush wear = 0.1mm/1,000h),
excellent no-load and very-low-current operation,
accepts high peripheral speeds,
makes it possible to reduce the IP protection index of the slip ring assemblies,
lower operating cost.

This combination of advantages makes the Carbon/Carbon solution the best for the Wind turbine application.
