How do you know how much withstand voltage the high-frequency transformer skeleton can withstand?

The compressive strength depends on the material and structure of the skeleton and the dielectric constant of the insulating material.

According to domestic suppliers, the withstand voltage of high-frequency transformer skeleton depends on the material, structure and dielectric constant of insulating materials. The commonly used materials of high frequency transformer skeleton are ferrite, permalloy, amorphous alloy and so on. The withstand voltage of ferrite skeleton is below 1000 V, permalloy skeleton is below 5000V, and amorphous alloy skeleton is below1000 v. ..
