Carbon Brush for Tachometer Generators

DAWOPU supplies a wide range of carbon brushes, both in copper- and silver-graphite materials. Manufactured to perform in extreme conditions, including cold and warm climates, low or high humidity, for onshore and offshore located wind turbines.

Dawopu develops brushes in close cooperation with several wind turbine OEM’s. Each brush is developed to match customer requirements. All Dawopu carbon brushes have been field-tested to prove high-quality performance in varying atmospheric conditions. The brushes are contamination tolerant, eliminating clog filters and preventing dust to sustain lifetime expectancy for your application.

4020-CMB7 is a high-performance copper-graphite carbon brush that can be successfully used for both power transfer and shaft grounding. The brush is slip-ring friendly and eliminates any wear or damage to the slip ring system. Patina is easily formed to maintain smooth current transfer and low friction in brush operation. 

An exceptional combination of high conductivity and low friction results in low electrical and mechanical wear of the brush and provides extended service life and high performance in operation.
