We Are Wherever You Are

Over 50 percent of the world’s electricity flows through our products. We take responsibility for the entire service life of our products – wherever they are used. We are therefore represented by 36 subsidiaries and six affiliated companies around the world to ensure the best possible service.  

Our Locations

We have 3,300 employees on five continents. With local service specialists, a spare parts service – even for products that were produced several decades ago – and training centers, we are never far away.


We produce on-load tap-changers, de-energized tap-changers, drives, oil filter units, and other transformer products at 10 locations.

Service Centers

We are represented all over the world with a total of 14 service centers. Over 150 certified service technicians are in the field around the clock. They are sent out over 4,000 times a year.

Training Center

To date, we have taught more than 14,000 experts from 170 countries in training sessions encompassing both theory and practice. There are now five certified training centers on four continents.
