ISMET builds air-cooled transformers, chokes and filters which are designed for use in E-mobility. ISMET also produces components required for interference suppression, such as sinusoidal filters, mains filters and mains chokes that are tailored and dimensioned specifically for the individual project.

In the medium-voltage range, we also provide three-phase cast resin medium-voltage transformers with a rated output of up to 5 MVA and voltages of up to 36 kV in order to cover the entire spectrum for use of renewable energies.


In the E-mobility segment, ISMET customer-specific solutions such as cast resin transformers/encapsulated transformers, chokes and power supply transformers, among other things, can be used.
