Input transformers made by Siemens in their own plants are very rare. According to the samples I have found I guess they started to use transformers made by Haufe for them in the late 50s. Later - in the early 70s - they returned to employ transformers from their own fabrication. Here you can see some of them - made by Siemens in Germany or by their Austrian section, the Wiener Schwachstrom Werke in Wien (Vienna). Please note that this site is under construction and may be updated soon. |
