Description

Vestas 753347 Earth Brush Holder is a complete grounding brush holder assembly for Vestas doubly-fed wind turbine generators. Manufactured with cast silicon brass housing, it offers excellent corrosion resistance and vibration resistance for offshore and onshore wind farm environments. Equipped with integrated stainless steel constant force spring, it keeps stable pressure on the grounding carbon brush during long-time rotation, ensuring reliable shaft earthing and eliminating shaft voltage to prevent bearing electrical erosion. Compact threaded mounting design allows quick field replacement and reduces turbine downtime. This assembly is commonly fitted on Vestas V52, V66, V80 and V90 wind turbine models. It is a critical spare part for wind turbine bearing protection, lightning protection and shaft grounding system. Made to match OEM dimensions and performance standards, ideal replacement for worn original Vestas 753347 earth brush holder.
