- A transmission line in which the conductors are in the form of bare, uninsulated wire. Materials such as ceramic, glass, or plastic are utilized to physically attach this wire to poles or another support, as such lines are always surrounded by air. Short circuits between such conductors are avoided by having the proper spacing. overhead lines are a common example. Also called open wire transmission line, open-wire feeder, open feeder, open line (3), or open wire (1).
