The invention discloses a recyclable 12kV current transformer. The recyclable 12kV current transformer comprises a 12kV main insulator (1), several ferrite cores (2) penetrate inside the 12kV main insulator (1), an operating rod (3) penetrates through the middle of the 12kV main insulator (1), the 12kV main insulator (1) is an insulating protection body, an inner shielding layer (4) is arranged inside the 12kV main insulator (1) and covers the operating rod (3) to separate the operating rod (3) from the 12kV main insulator (1), and a skirt side (5) is arranged at the bottom of the 12kV main insulator (1). By means of the recyclable 12kV current transformer, an insulating part is made of a thermoplastic insulating material, so that the 12kV current transformer is recyclable, the using costis greatly lowered, and the environmental pollution is reduced.
