From compact distribution to large power transformers with ratings over 1000 MVA – choose from our broad portfolio to get the right product for your requirements!
Success story, May 29, 2017
The Ximeng-Taizhou project relies on highquality transformers from Siemens, the most innovative supplier of power transformers.
A key role in electricity supply
In March 2017 Siemens was honored with the IF award for its innovative transformer design. Along with the eye-catching layout of its transformers, Siemens now announces the renaming of two product lines: FITformer and GEAFOL Neo. FITformer is the name of the transformer family now congregating all liquid immersed distribution transformers while GEAFOL Neo is the modern version of the current GEAFOL Basic. The new brand names reflect Siemens’ innovation leadership and top-end quality. Siemens FITformer and GEAFOL stand for eco-friendliness, high efficiency and maximized availability. While the names and visual appearance of our products will change, our expertise and quality remains the same.
Reliability of energy grids is a matter that effects everybody involved in the business. Siemens Transformers offers a whole portfolio to offer grid resilience wherever needed. Our concept, named Pretact®, for resilient grids comprises a three-pillar-plan to enable our customers to prevent failures, protect their equipment and react in cases of emergency. Learn more on this topic in our infographics, use cases and collaterals. Our new concept addresses emergencies, retrofits and new installations along the entire energy value chain to increase network stability by modular feature/ solution architecture for power and distribution transformers.
The idea of mobile resilience units is to replace a large EHV-transformer by three compact and versatile single-phase units – either for planned or unplanned outages. The transport and installation can be completed within 30 working hours.

Have you ever asked yourself why a transformer looks the way it does? The most innovative engineering, materials and technologies are hidden inside. We have decided that in future our leading electrical and mechanical design should be visible from the outside.
Honored with the coveted iF Design Award 2017: the Transformer Family Design and the Design of the Mobile Resilience Unit as part of the Pretact® Concept.
As of July 2015, distribution and power transformers put into service within the European Economic Area (EEA) must comply with the new requirements of the Ecodesign Directive from the European Commission. The directive aims to improve energy efficiency, environmental compatibility and thus to reduce CO2 emissions. Siemens transformers can be designed to fulfill the new EU requirements.

Fields of operation
In more than 100 countries and for more than 100 years, transformers made by Siemens have been synonymous with top quality. The extreme high reliability (mean time between failures) is only one example of this quality. To ensure things stay this way, we are constantly working with high level experts on research and new developments. Furthermore, we are always close to our customers – thanks to our global manufacturing and service network. See for yourself, why our transformers make a difference!
