Description

The Carbex 2008-40-SW-KIT is a complete pre-assembled carbon grounding brush kit specially designed for wind turbine shaft grounding systems. Made of premium silver graphite material, it delivers ultra-low contact resistance, excellent electrical conductivity and self-lubricating sliding performance. The grounding brush safely bleeds harmful stray shaft currents away from generator bearings to ground, avoiding electrical erosion, pitting and premature bearing failure, which greatly reduces wind turbine downtime and maintenance cost. This kit comes fully assembled with carbon brush block, constant force spring and flexible copper lead wire, radius R70mm profile to match turbine shaft surface. It is widely used on Siemens, Nordex, Senvion, Loher, Winergy and VEM wind power generators. It serves as a drop-in replacement equivalent to Schunk S13/F19 and LFC554/A620. Stable performance is maintained even in harsh offshore high humidity, temperature-varying environments. Strict quality control ensures consistent wear rate and reliable long-term grounding performance. Bulk supply and worldwide shipping available for wind farm maintenance and OEM service.
