DC-3,5/10(G) single phase and casting transformer
一、 Description
    The product is used for self - use transformer 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 dis-charge, low impedance volLage and conveniently fixed. It is the first choice for replacing three phase and oil-filled transformer.
