DC-3/20 Single phase and casting transformer
一、 Ceneral
    The product is used for self - use transfonner in the power distribution station to provide power charge,
operation control, signal and protection, It is small and light. It has many merits, such as: no partial discharge, low impedance vohage and conveniently fixed. It is the first choice for replacing three phase and oil-filled transformer.
