Notes:
The load loss values listed in the table correspond to different insulation systems at the reference temperatures specified in parentheses in GB/T1094.11. Load loss values for other insulation systems not included in the table shall be converted according to their respective reference temperatures, using the data for the 155℃ (Class F) insulation system as the reference.
