Blue portfolio – increase sustainability of switchgear 

Our “blue portfolio” makes it possible to modernize and expand the existing power grids at the highest level of safety and to simultaneously reduce our ecological footprint to an enormous extent without having to compromise on performance and economic feasibility. The products are perfect for frequent switching applications, very reliable and maintenance free..

Our “blue portfolio” includes gas insulated switchgear, circuit breakers and instrument transformers, surge arresters and bushings.

Ester technology – increase sustainability of transformers

Synthetic and natural esters are beneficial alternatives to mineral oil as an insulating liquid in transformers. Their biological degradability make them extremely well suited to applications in environmentally sensitive areas. 

There are many operational advantages of using ester as an insulation fluid in transformers as well. For example, its high fire and flash point improves the fire safety of the transformer. Besides ester fluids can extend the lifetime of a transformer and eventually lead to smaller footprint of the transformer station.

Resilience: Pretact® – React in advance

Reliability of energy grids is a matter that effects everybody involved in the business. Siemens Transmission Products 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.
