The data in the catalogues(see list in table on the back page) apply to transformers in the range of system highest voltages 3.6...24kV as given in the table on the facing page. The nominal low voltag is 400 V. Reconnectable high-voltage windings with a ratio of 2:1 or even less (e.g. from 10 to 6.3 kV) and deviating low-voltages can be provided. The tapping range is + 2 x 2.5% as per DIN 42523 and 42524. Transformers with the following formerly used tapping ranges can also be supplied:
