Energy distribution

ISMET high-performance high-voltage transformers for energy distribution with rated outputs of up to 600 kVA for input voltages of up to 20 kV and output voltages of up to 15 kV. The one-phase and three-phase high-voltage transformers can be provided in open design, in a housing or in a cast resin enclosure and achieve protection ratings of up to IP54.

In the medium-voltage range, we cover a wide spectrum of applications with three-phase medium-voltage cast resin transformers with a rated output of up to 5 MVA and voltages of up to 36 kV. Our three-phase cast resin transformers are distinguished by low maintenance requirements and a low risk of fire. They are also suitable for demanding environmental conditions. High surge and switching voltages and short-circuit peak loads are not a problem. We can also build larger customer-specific one-phase and three-phase transformers with a rated output of up to 3 MVA and forced air cooling, direct water cooling or indirect water cooling for your energy distribution.


In the energy distribution market segment, ISMET customer-specific solutions such as water-cooled transformers, chokes, cast resin transformers / encapsulated transformers coupling inductors, among other things, can be used.
