The first: Voltage distribution on Insulator. Here is an Insulator chain, it hold an steel pipe, it is the wire model, it get the high voltage. The voltage is 0-25 kV. There in an wie with banana plug on the Insulator's cup and the next end of wire is a box with a glimm lamp. The glimm lamp light up on a fix voltage, about 600-700 V, and we can measure it. We measured every metal part of Insulator chain, every part made glimm light. The consequence: The first part of the Insulator get the all voltage's (!) 45-55 %. It is very hard think, we must scale over x4 x6 the Insulators!
