Product Overview
This amorphous alloy oil-immersed transformer uses amorphous alloy as core material, with insulating oil for cooling and insulation. It features extremely low core loss and remarkable energy saving. The fully sealed structure prevents oil leakage with maintenance-free performance. Low temperature rise slows insulation aging, suitable for outdoor power distribution, industrial & commercial sites and new energy projects. It is eco-friendly with lower overall power consumption during service life.

Notes:
①For a three-phase three-limb core, Yyn0 connection group mayalso be adopted as required.
②For transformers with rated capacity up to 500kVA, the load loss values above the slash in the table apply to Dyn11 or Yzn11 connection groups; the load loss values below the slash apply to Yyn0 connection group.
