rovide single phase supplies for train overhead systems. The duty of traction supplies transformers is a particularly difficult one, as overloading up to twice full-load current can appear. Furthermore, trackside transformers need to withstand system short-circuits which may be as high as 250 per year of varying magnitude up to full fault current. Height of the unit is reduced by mounting the active part horizontally. We have a wide range of uniquely designed products with advanced design techno
