Magnetic Properties
powercore®
thyssenkrupp Electrical Steel’s high-tech core material powercore® has been largely responsible for increasing the efficiency of power and distribution transformers.
The use of powercore® can also significantly reduce total manufacturing costs for transformers, a major advantage in the face of rising raw material costs.
powercore® is the core material for the future!
Cost benefits due to:
- lower core weights
- more compact dimensions
Higher energy efficiency due to:
- minimum no-load losses
- better capitalization of losses
Reduced noise emissions due to:
- optimized magnetic domain structure
- improved insulation properties
