You could use insulated wire for the inner conducture...stripping off the
below where the salt water meets the oil...this would give you back the 3 lost
inches of creep path. Having a cork to hold the wire in the center will
help...make sure the cork has a small vent hole..... about this size
I suppose there is 40kv insulated wire...though I've only used neon wire off of
15kv trannys...I dont know its voltage holdoff rating.
