VACUTAP® VI

The evolution of our proven vacuum technology

The VACUTAP® VI is an innovative on-load tap-changer in vacuum technology that is used in small and medium-sized power transformers. It impresses with material savings - also on the transformer - as well as with simplified customer interfaces during installation and commissioning.

Your Advantages at a Glance

  1. Common oil compartment of the tap-changer with the transformer and thus saving of components e.g. OLTC oil expander etc.

  2. Smaller transformer possible for the same power or identical size for higher power.

  3. Simplified line routing due to uniformly side-positioned winding connections.

  4. Reduced installation effort and automated commissioning via the control system.
