1. The core of the current transformer has adoped amorphous alloy, it has high magnetic permeability, low saturation induction density and good stability.
2. High quality silicon steel sheet is taken to be the core of windings protection, which ensures the high accuracy limit factor.
3. The circular ring core and secondary windings are poured by high quality expoxies resin or polyurethane or silicon rubber in the fire retardant plastic casing, which has the characteristic of moisture proof, stable performance and dispensing with maintenance. the cable can cross the current transformer through its internal poles quickly and uniformly.
