Are you looking for vibration damper or insulator for 800 KV? How much vibration does it create? I am trying to understand the specifics. If you are looking for electrical insulation and vibration damping, I would recommend reinforced EPDM rubber (non-black with 25% blend with SBR) about 0.75 inch in thickness and that should serve for both - Vibration damping and Electrical insulation ---- Measure damping factor by DMA (Dynamic Mechanical Analysis) and Dielectric Strength --resistance ---Volts per Mil.

Also, First you must know how much vibration does it create? It depends upon many factors such as wiring jackets, voltage, type of wire/conductors etc;-------So You need to find and come up with a number for damping co-efficient before you proceed further--

hi,

you can find the how-tos from the following sources:
