Structure and Feature
This type assembled transformer is builtup by two single-phase voltage transformer and two current transformer. It takes transformer oil as insulating medium. Primary and secondary outlets are mounted on the panel seperately by porcelain bushing shell and secondary outlet board. There are mounting holes on the bottom of the oil box. This type has advantages of high calculation precision, light weight,easy mounting and thief-proof.
