The current transformer features a whole-sealed structure with epoxy resin as its main insulation. Its core adopts crystallitic alloy or high-quality silicon steel sheets wound into an annular shape. Secondary leads are wound evenly, and primary conductors are protected by insulation belts to prevent short circuits. Earth bolts and mounting holes are provided at the bottom for secure installation.
