Update on EU's anti-dumping-regulation for electrical steel

Starting Nov. 13th, there will be a change in the anti-dumping-process that started in May 2015. The European Commission will introduce a new regulation that focuses on minimum price levels for grain-oriented electrical steel (GOES). These measures will apply to imports from China, Japan, Korea, Russia and the U.S. The minimum price levels differ for different grades of steel set by the EU and must be kept, otherwise anti-dumping duties of up to 39 percent will be imposed.

Siemens Transformers is working on keeping the impact as low and transparent as possible for our customers.

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.

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.

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 PretactTM, 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.

Visual Design

Shaping the future of transformers!

Shaping the future of transformers!

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. Shape the future of transformers with us by answering our survey.

What our customers think:

The new shape is very nice, looks strong, powerful and modern.

A compact, stable, powerful product.

I must confess that as an old transformers guy, I like to see new ideas and innovation also on the exterior of power transformers. We all know that quality transformers are packed with high tech materials and know-how, so why should it not be visible on the outside? Nice initiative!

Fields of operation

Find out why our transformers make a difference

In more than 100 countries and for more than 100 years, transformers made by Siemens have been synonymous with top quality. The extremely low 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!

Green Transformers with ester insulation

Synthetic and natural esters are beneficial alternatives to mineral oil as an insulating liquid in transformers. Their high flame and flash point as well as their biological degradability make them a shooting star among the cutting-edge transformer materials available nowadays.
As a brand new innovation using synthetic ester, Siemens Transformers has manufactured and successfully tested three power transformers for the 400 kV-level with synthetic ester insulation and waste heat usage.

Handling three different voltages at once

Amtrak ordered 70 high-speed, electric locomotives with traction transformers from Siemens. The challenge: They have to cope with the three North-American UIC voltages of 25, 12.5, and 12 kV. Siemens countered this problem with its 3-system transformer: The voltage change between the three UIC voltages is not performed in the conventional way on the low-voltage side, but rather on the high-voltage side of the winding.

Reliable power transmission from New Jersey to New York City

How do you provide sufficient and reliable power for a megacity like New York? Hudson Transmission Partners, LLC, awarded Siemens with the contract to connect the power supply networks of New Jersey and New York for a 660 MW back-to-back HVDC system. The challenge has been to provide a stable interconnection of two independent grids in an area with limited space and restrictive noise requirements, all within a short time. Eight Converter Transformers for HVDC Transmission helped to master this challenge and to ensure a reliable power supply for New York City.

Transformer shipment through the Alps

Siemens is dedicated to getting your product back into shape – even if it weighs 360 tons and has to be transported through the Alps for inspection. The 600 MVA ELIN transformer had been used by APG, an Austrian grid operator, since 1989. After experiencing an external flashover in 2011, it was brought from Salzburg, Austria, all the way to the Siemens production plant in Weiz, Austria, for inspection. Having a life expectancy of a completely new transformer after the repairs, Siemens discharged the patient and transferred it 200 kilometres through the Alps to its new site of use in Ernsthofen, Austria. This special service was included as part of the maintenance contract.
