Chris,

TC voltages and frqiencies are hard to insulate as im sure you know... :) I
would go for the lexanm not the HV bushing. You will probably need to put
the wire in an oil filled pipe and then pass the whole thing through the
lexan.. if the roof is wood watch out for corona off the nails and fires,
etc..
