A key role in electricity supply

Current highlights

Direct-current electricity can now be transmitted at gigantic 1,100 kilovolts

The world´s first transformer, which has been designed and manufactured for the HVDC transmission line with the highest direct-current electricity of ± 1,100 kilovolt (kV) has been tested successfully in Nuremberg, Germany. The transformer will enable low-loss and extremely efficient high-voltage direct-current (HVDC) power transmission over a record distance of 3,284 kilometers with a transmission capacity of twelve gigawatts.

 

Excited? You can watch part 1 and part 2 of the entire films on Siemens’ first 1,100 kV HVDC transformer on YouTube.

Find out how our innovations are shaping the future of transformers

There’s so much more to a transformer than just transforming voltage: They actually form the backbone of modern energy grids, and their reliable operation is crucial to ensuring a stable and resilient power supply.

 

If you haven’t had the chance to see our transformer model in person, now you can learn all about innovative transformer technology from wherever you are by watching the playouts online.

Innovative traction transformers “Tractronic® Thinity”

image

Siemens presents its latest innovation highlight: The Tractronic® ThinityTM transformers will be installed in the trendsetting Siemens regional train platform Mireo®. The highly innovative transformer design results in an ultra-low weight of the infinity-symbol shaped Tractronic® ThinityTM transformer (approx. 25% less weight). The decreased weight will not only make the trains less energy-consuming. There will also be a higher capacity for passengers, monitoring equipment and passenger infotainment on board. Further benefits of the development are: more freedom of movement, shorter construction times, and optimized components – together these aspects form the truly unique Tractronic® ThinityTM transformer.

Distribution transformers in new clothes

image

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. 

Resilience: Pretact® – React in advance

Keeping grids resilient - at any time with Siemens Transformers

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.

Installing a mobile resilience unit within 3 days

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.

Ecodesign

Check your transformer’s compliance with EU requirements

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.

Does your transformer’s Peak Efficiency Index satisfy the new EU requirements?  

The entered values equal a Peak Efficiency Index of

Target value:
Your transformer satisfies the new EU requirements and is ready for action!

If you still have any doubts or questions, we are pleased to help you.

Your transformer does not satisfy the new EU requirements and is not allowed to go in operation within the EEA. The loss level has to be decreased.

We are pleased to help you with any questions or further information.
