According to the actual delivery process of the project and the specific / severe ambient conditions on site, the BRUSH generator's rotor was seriously rusted. The mechanical engineer from the Roerbough team cooperated with BRUSH European colleagues to complete the maintenance and repairment of these two BDAX 7-290ERJT generators on site, such as rotor extraction, rust removal and reassembly, to ensure that the generator quality meets the requirements for normal operation
