Justin,
 
Actually PVC has enough permeability to water that the oil will eventually be
contaminated with water.  This unsuspected event poses a real HV danger.  Also
you have several dielectric interfaces such as oil-PVC and PVC-air which will
become contaminated with moisture.
 
A single failure will probably be fatal.  There are no dress rehearsals here.
