An
aerial cable or
air cable is an insulated cable usually containing all
conductors required for an electrical transmission system or a telecommunication line, which is suspended between
utility poles or
electricity pylons. As aerial cables are completely insulated there is no danger of
electric shock when touching them and there is no requirement for mounting them with
insulators on pylons and poles. A further advantage is they require less right of way than overhead lines for the same reason. They can be designed as
shielded cables for telecommunication purposes. If the cable falls, it may still operate if its insulation is not damaged.
