Reliable, long-lifecycle solutions built to customer requirements

For more than a century, power suppliers and industrial companies have relied on Siemens for its reliable and efficient power transformers. Almost all of them, ranging from power ratings from 20 MVA to units well above 1,000 MVA,and 20 kV to 1,100 kV are tailor-made.

 

Siemens offers a complete chain of services – from consulting to design, from manufacture and transport to commissioning and Transformer Lifecycle Management. As one of the leading transformer manufacturers worldwide, Siemens Transformers offers a tight and responsive competence and service network in more than 190 countries in the world.

Daily savings

Siemens Transformers' services and products ensure daily savings for customers: There are the savings in capital expenditure for regional manufacturing plant setup and for acquiring the broad experience and in-depth knowledge required for creating custom unit designs. The benefits of minimized failure rate and losses, low-noise transformers, units with DC compensation, and monitoring systems for preventive maintenance, on the other hand, translate into savings in operational expenditure.

Minimized risk of failure

Siemens power transformers can be integrated into any kind of power management system. You can opt to integrate them into any cloud-based monitoring system, such as MindSphere. This gives you insight into the current operating condition of the transformer and critical loads, thus facilitating the prevention of power outages.

 

 In addition, Siemens Transformers offers a comprehensive Pretact® solution, designed to maximize grid availability by minimizing the consequences of both unplanned outages and planned outages. 

 

Making the most of its decades of experience in manufacturing and managing low voltage to extreme high voltage levels, the Siemens portfolio offers highly reliable transformers, from distribution to HVDC transformers, with minimized risk of failure and maximized availability.

Investment pay-offs

Siemens power transformers come with strong investment security. State-of-the art transformer applications, such as variable shunt reactors, phase shifters, support customers in providing improved power quality. 

 

Operators can leverage Siemens transformers to increase capacity utilization and to optimize grid operation. A reactor, for example, can transmit more energy over existing lines, or a phaseshifter can be used to optimize load flow. Siemens not only builds retrofits with latest-technology transformers to replace old units but also offers interesting project financing solutions. 

 

Environmentally friendly

CO2 reduction

Replacing older applications with more powerful transformers using the latest technology substantially reduces the carbon footprint.

 

Ester insulation

Siemens offers both natural and synthetic environmentally friendly ester insulation for all transformers, including reactors, phase shifters, and HVDC applications.

 

Benefits of ester insulation

  • High flash- and fire point for increased safety
  • Readily biodegradable liquid for extended environmental protection
  • High moisture tolerance for a long lifetime
  • Possibility to increase transformer loading
  • Synthetic ester: low pour (-56°C) point allows operation in cold climates
  • Lower costs thanks to decreased risk of fire and longtime outages due to hazardous failures.

Certified quality standards

A strong Siemens transformer factory network around the globe creates leading transformer technology and pre-manufactured components. Siemens gobal footprint with transformers experts familiar with both local and international requirements also ensures customers enjoy fast response times and on-time delivery. In committment to quality without compromises, the quality management system used across all plants manufacturing Siemens power transformers complies to DIN ISO 9001:2000.

 

To meet public local content requirements, Siemens also enables and supports local transformer manufacturers to produce transformers based on Siemens technology. However, to ensure a consistently high transformer reliability, Siemens Transformers implements in-house prototype design and manufacturing.
