    Distribution transformer (Standard)

    Oil-immersed transformer, which uses insulation oil is ordered and produced by reflecting the needs of consumers to satisfy consumers maximally.

             

    (1) Reliability

    It has the reliability because of its own optimal cooling design and Insulation design with electric and magnetic interpretation technology.

    (2) Compacted design

    Coils have different types and method accordings to the quantity, voltage and use, and the size of conductors is decided to stand electromagnetic force occurring on the accident of current carrying capacity, temperature rise and external insulation.
