Plastic caps rating

Subject: Plastic caps rating
This is an open letter to anyone who presently owns a Plastic Capacitors cap
- or who has good advice on this subject.
I would like to know what the AC RMS voltage rating is on your cap and what
AC supply voltage you use.
As I mentioned, I am in discussion with Tom Brown at Plastic Caps and it
seems that we can get a 27 kv ac rms rated .030 mfd cap for $313.00 or a 30
kv ac rms rated .030 mfd cap for $410.00. The higher voltage rating forces a
step up in case size and increases the cost quite a bit for only an increase
in rating of 3 kv.
My supply is a 14,400 volt pole pig. Using the extra tap on the powerstat, I
can raise this to a maximum of 18 kv. Am I safe using the 27 kv rated cap??
Would Charles Brush be safe using the same cap with his 20 kv pig??
Thanks for the help - Ed Sonderman
