Short-circuit strength

This test is performed within the scope of type tests, however, it can also be carried out in well-known and reputable test laboratories on request.
After long-standing testing practice as well as positive experience on the part of our clients, the use of a cylinder block stuck to LV windings in combination with the HV layer windings has proved to be problem-free.

Quiet transformers are part of our checklist
|
|
Reducing the noise emitted by the transformer in the environment is becoming more and more important.
Therefore our oil distribution transformers also offer – besides the standard design acc. to DIN 42500 – reduced losses and noise levels too.
In addition to the choice of flux density and core material, the step-lap technique of joining the legs and yoke also reduces noise levels and no-load losses in SGB transformers.
