Specifications for outdoor 15kV post insulators - how do you specify creepage distance?
(OP)
We're looking over the specifications for some replacement post insulators that a vendor has quoted. Our operationg voltage is about 15kV. He qouted one that is rated 15kV and the creepage distance is about 20". He also quoted a 35kV insulator whose creepage distance is 31". Can someone explain what this is referring to...? And how do we know we are getting the right one?

It is not the straight line distance from top to bottom which is referred to as the strike distance.
