RE: Pri/Sec Insulation for maggy

I guess it really depends upon the dielectric strength of the plastic. You 
never said what material it was exactly. As you know there are thousands of 
different types of plastic and all of them have different electrical 
properties.  X-ray cable rated at 140kV continous use and it only has about 
5/8" of insulation covering the conductor it is tested to almost 300kV. 
Based on this information I'd have to say that 5/8 should be enough if the 
plastic has a good dielectric strength.
