Huh?

Yes I am familiar with the trick of adding ridges to reduce insulator voltage leakage. Just look at any power substation.

But do you honestly think that 1/16 in ridge on some octal is doing the same? I sincerely doubt it. It's for mechanical rigidity as far as I can see. after all Bakelite and Phenolic are quite brittle.

It's just cowboy logic again to make such an extrapolation without some solid data behind it.
