Product Structure
YDJ (Z) series power frequency voltage test transformer adopts single frame core-type iron core structure. Primary winding wound on the core, high-voltage winding outwards, the coaxial arrangement reduces leakage flux, thus increasing the coupling between the windings. The housing plus the internal core is made into octagonal structure, with very nice appearance. Its external structure shown in Figure 1, the internal structure shown in Figure 2.
