An ABB transformer data sheet includes electrical ratings (kVA/MVA, voltage levels, vector group, frequency), insulation levels (BIL/LI), impedance, losses (no load and load), tap changer details, cooling class, temperature rise, dimensions, weight, oil volume, sound level, standards compliance, and optional monitoring devices. It may also show accessories, design variants and manufacturing tolerances. Utilities use these data sheets to compare units, verify compatibility and specify procurement requirements.
