Transmission tower in Toronto, ON Single-circuit three-phase transmission line Transmission towers on a hill field. Three-phase electric power systems are used for high voltage (66- or 69-kV and above) and extra-high voltage (110- or 115-kV and above; most often 138- or 230-kV and above in contemporary systems) AC transmission lines.
The cables holding their platform were found to have slipped, causing Edgar to plunge 472 feet and land on a fence, killing him. Alcides, meanwhile, reportedly managed to hang on to the platform ...
