Structure and Feature
This type assembled transformer is totallyenclosed outdoor oil immersed structure, mainly 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. The oil box and insulator are full of transformer oil. There is oil level indicator on oil conservator. There is oil drain at the the oil box. Is has mounting holes at the bottom of oil box. This type has advantages of high calculation precision, light weight,easy mounting and thief-proof.
