Railway infrastructure

ISMET has a wide product spectrum to offer for railway technology ranging from inductive components on the static inverter and commuting chokes to high-voltage technology for railway electrification. We build one-phase and three-phase transformers for rated outputs of up to 20 kW in an open design or in a housing – in a railway-suitable design and in protection ratings of up to IP 54 and with up to isolation class H, if necessary. Special transformers for railway control centre technology are part of the ISMET Offering for railway technology.

Power supply transformers for outdoor use and use under unfavourable environment choices are the right choice for use along the route.


In the railway infrastructure segment, ISMET customer-specific solutions such as chokes and power supply transformers, among other things, can be used.
