[Table 1] shows the test report of our company (applicant) developed of the earthquake-resistant mold transformer (1,000 kVA).

Referring to Table 1, it can be seen that the resonance frequency is lower in the Y axis than in the X axis and the Z axis. The low resonance frequency means that feedback is low when an external force is applied to the object, and the low feedback means that the mold transformer is ductile, and ductility means that many deformations it means.

Therefore, as shown in Table 1, the mold transformer of the above-described structure has a lower seismic performance in the Y-axis than the X-axis and the Z-axis, and it is necessary to strengthen the seismic performance of the mold transformer in the Y- Respectively.
