Technological properties

Application areas

Large power transformers, distribution transformers, small transformers, current transformers, shunt reactors, wound cores, power generators


Both sides coated, coating thickness: 2 µm - 5 µm


Advantages of powercore®: Energy efficiency thanks to minimal losses at full load and reduced no-load losses, reduced noise emission thanks to minimized magnetostriction and improved insulation properties, cost benefits thanks to lower core weights and more compact dimensions.
