It should be determined based on your electrical conditions
Theoretically, a silicon core with a high resistivity implies high purity, but it depends on the resistivity of the silicon material produced. If the resistivity of the produced silicon material is not high, then there’s no need to use a silicon core of very high purity； Furthermore, a higher resistivity makes it less likely for breakdown to occur. It depends on whether the breakdown happens at high voltage or medium voltage; in the case of medium-voltage breakdown, preheating the silicon core is usually necessary, and good preheating results are required for the breakdown to take place.
It’s related to your system; it’s not necessarily the case. All of the reasons mentioned above apply, and there are also other minor details – it can’t be generalized
