I'm not sure I understand your questions.

Arcing distance is generally the distance in which an arc will initiate in air at 1 atmosphere with some moderate temperature with a range of humidity. Creepage is similar except it is the distance between conductors adjacent to some insulating surface.

In the case of creepage distance across some insulator, if I'm not off base, is a function of how easily that "insulator" becomes ionized, thereby creating a conductive path.

Did this answer your questions?

Consider the shape of a ceramic insulator. Why is it shaped like it is?
