These transformer magnetic cores serve power transformers from 16 to 16,000 kVA, manufactured in dimensions from 300×100×300 mm up to 5,000×2,400×5,000 mm and masses from 50 kg to 30 tonnes. The magnetic core is the heart of every transformer — stacked or wound electrical steel whose geometry and lamination quality determine losses, noise and efficiency across the unit's decades of service.
Core production at this dimensional range requires specialized slitting, stacking and annealing capability that few suppliers maintain, making qualified core sources strategically valuable to transformer manufacturers. At about USD 300 entry price with single-unit MOQ, the products serve transformer plants, repair workshops rewinding distribution units, and electrical OEMs developing special-purpose magnetics.
The manufacturer works from customer drawings or designs cores to electrical specification, supplying lamination stacks with documented steel grades and loss characteristics that transformer designers need for performance guarantees.
