Siemens Transformers.
From the simple instrument transformer to today‘s high-tech product – the history of the transformer is full of trailblazing
inventions and innovations. Always a leader in development: Siemens is a pioneer of the transformer technology.

Transforming knowledge into first-class products.
Siemens Transformers.
Why Siemens transformers are held in such high regard throughout the world can be explained very easily:
because of the proven reliability in decades of continuous operation – often under the most demanding
environmental conditions. The basis for this success is the acknowledged high quality of design and construction.
