    Oil-immersed type

    Energy-saving oil-immersed transformer with more than 75 percent reduction of no-load loss using amorphous metal instead of silicone sheet.                

    (1) No-load loss reduction

    Minimal no-load loss by amorphous structure and super-laminate metal pin materials

    (2) Economic efficiency

    "Operation and maintenance cost decrease and life extension expectation of transformer by the loss reduction"

    (3) Harmonic wave reduction

    High Efficiency and compactification by excellent magnetic characteristics in the high frequency and harmonic wave band
