We invented the on-load tap-changer, and pioneering innovations are still coming to us all the time.
Beginning with OILTAP® technology, we were the world market leader in transformer tap-change operations.

Our VACUTAP® technology revolutionized the on-load tap-changer yet again. Because the tap-change operation happens in a vacuum, our products are generally maintenance-free, which allows the life cycle costs of our customers to be drastically reduced.

Today, our wide product range includes vacuum switches for all types of transformers and applications, from network transformers to special applications.
Five reasons why you should choose MR on-load tap-changers:

1. unmatched experience

2. superior technical solutions

3. multi-certified quality

4. excellent lifetime support

5. full system capability
