Curves connect source data points only. Missing values break the line.
Core manufacturing
Need a transformer core made to these material parameters?
Chenfan Electric manufactures custom CRGO transformer cores to customer drawings, including step-lap cores and ready-to-assemble core assemblies.
- Precision cuttingBurr height < 0.02 mm
- Controlled stackingStacking factor 0.96–0.97 (depending on thickness)
- Made to drawingManufactured to customer drawings
Technical note
Material performance is the starting point
Actual transformer core performance also depends on joint design, step-lap geometry, cutting accuracy, burrs, stacking quality, mechanical stress, flux distribution and manufacturing processes.
Chenfan Electric can manufacture transformer cores to customer drawings and specified CRGO grades.
These data describe CRGO material properties. They are not the no-load loss of a finished transformer core.
Performance data are for engineering reference only. Actual transformer core performance varies with material batch, cutting, joint design, stacking, stress and manufacturing conditions.
