It being non-conductive is one immediate advantage.... Also if your grounding is inadequate you may like to take a squiz at the ISO or TIA Standards as they pertain to cabling. In NZ we have a variety of standards which all point back to ISO, the ANSI equivalents are TIA/EIA 568-B (Cabling), TIA/EIA-569-A (Pathways and Spaces) and TIA/EIA-607-A (Electrical Wiring, relevant as it pertains to Earthing etc). Even for short runs, If I need to run between buildings externally I won't even look at copper. Mark.
