1. A system for de-icing a surface of a cableway system component comprising:

  • an electrical conductor proximate to, but not in contact with, the surfaces,wherein the electrical conductor is not configured to encircle the cableway system component; and

    an AC power source for providing a high-frequency AC voltage in the electrical conductor that generates a high-frequency alternating electric field at the surface sufficient to melt ice at the surface.
