Product description

The VACUTAP® VR® is the world’s first on-load tap-changer which is maintenance-free up to 300,000 switching operations. The figure for the VR I HD is 600,000 tap-change operations. Since its maintenance is no time-dependent, your transformer has much less downtime.
In addition, you take advantage of the many possible applications of the VACUTAP® VR®. It is the first choice for auto transformers, HVDC transformers and many other applications.
