So, how do insulators on the guy wire (especially if the guys are  
phillystran or fiberglass rod) prevent galvanic corrosion of the guy  
rod in the earth?

 From what I understand of reduction-oxidation (redox) reactions,  
ions in the soil will attack the metal ions in the guy rod just by  
being in contact.
