One of the main problems OEM’s experience on a wind turbine is the gradual build-up of electrostatic charge, if this issue is not addressed with a professional solution the electrostatic energy can cause detrimental damage to key nacelle components.
It is not uncommon for energy to be discharged through the main shaft bearings. Over time this creates defects in the main bearing races leading to a turbine failure and in offshore environments, changing main shaft bearings can be a very costly exercise.
BGB have developed a specific brush composition that discharges any electrostatic energy down to earth operating on the main shaft and providing a reliable solution. The Ground Contact design is retrofittable to the main shaft of a turbine.
Partner this product with BGBs dedicated lightning brush holders to help protect sensitive components within the nacelle.
