The right Power Transformer for your task
Bringing the energy safely to the consumer: A basic requirement applicable to all Power Transformers. However, every single one is unique – designed according to individual factors such as voltage, power, climate, system topography, sound level and many more. Siemens is your partner, who picks up these requirements converting them into convincing solutions with maximum quality. Power Transformers that render their service reliably at site. Cost-efficient and safe throughout decades.
Siemens offers a complete service – from advice and design via manufacture, transport and commissioning up to our Transformer Lifecycle Management. Find out more about the layout and components of Siemens Power Transformers by clicking on the tabs above.
The precision of core manufacture is a decisive factor for the later efficiency of the transformer. Siemens Power Transformers are manufactured as coretypes, with the limbs arranged at the same level and interconnected via yokes.
We are using high-grade cold-rolled laminates of transformer steel. Depending on the requirement also lasertreated ones.
When cutting the laminates, we rely on most modern numerical control systems, enabling the so-called step-lap-technique, with the consequence of an especially appropriate flow of characteristic within the core of a Power Transformer.
For high electrical and mechanical stress windings in Power Transformer are made of disc coils; for low voltages the use of layer windings has proven successful.
To adjust the ratio safely and easily to system conditions, Siemens Power Transformers have tapped winding. In this way the ratio of Power Transformer can be changed gradually - either in no-load condition via off-load tap-changers or under load by means of on-load tap-changers.
Another main component besides the core and the winding is the tank of a Power Transformer: It accomodates the active part and the oil filling.
The core, windings, pressed parts, tap-changer and connecting cables make up the active part of the Power Transformer.
The drying of the active part is done according to the vapor phase procedure.
After that the active part is installed in the tank and filled with high-grade insulating oil under vacuum. The transformer is now ready for testing.
