Notes: The load losses listed in the table are the values of the reference temperature for different insulation systems in parentheses; The load losses under other insulation system temperatures that are not included in the table should be according to their respective reference temperatures, the corresponding calculation is based on the"- 155 ℃ (F)" insulation system temperature data.

Notes: The Dimension and weight will be changed according to the requirements. These two data in the table will be subject to the factory documents.
