Primary Winding:
A high-electrolytic copper primary winding is used, and a silver-base welding material is used at the welding place. Semiconductor shielded paper is wrapped around it to ensure that the partial discharge testing data is qualified.
Secondary Winding
The large-capacity secondary winding is automatically wound with high-insulation, high-purity enameled wire to ensure a wide capacity output under standard accuracy.
