By Voltage Class – Core Size & Magnetic Flux Density, to classify cores of transformer
· Low Voltage (LV): Up to 1 kV
· Medium Voltage (MV): 1 kV – 69 kV
· High Voltage (HV): 69 kV – 230 kV
· Extra High Voltage (EHV): >230 kV
Large cores require careful control of magnetostriction and joint losses. Domain‑refined GO is often used to reduce no‑load loss, a major part of lifecycle cost.

By Cooling Method – Thermal Management, for classification of transformer cores
Cooling method (ONAN, ONAF, OFAF, etc.) does not change core material but affects temperature rise. High‑cooling designs allow higher flux density since heat is removed more effectively. GO with stable magnetic properties up to 100–120°C ensures performance across all cooling regimes.
