Bipole I & II Spacer Damper Replacement
Rokstad Power was selected by Manitoba Hydro to conduct the removal and disposal of 56,560 spacer dampers and the installation of 61,250 new spacer dampers on the existing Bipole I & II 500kV HVDC Transmission Line under live line conditions. Crew members and their equipment are helicopter hoisted onto the line using a Bell 212 helicopter. This process plays an essential role in increasing Rokstad Power’s productivity to allow for completion of the work in a short period of time. The helicopter method also avoids environmental impacts by limited ground-based access requirements.
