First 735 kV AC Transmission System
Society: IEEEMain Category: ElectricEra: 1960-1969DateCreated: 1965Hydro-QuebecMontréalState: QuebecCountry: CanadaWebsite: http://www.ieeeghn.org/wiki/index.php/Milestones:First_735_kV_AC_Transmission_System,_1965Creator: Hydro-Quebec

Hydro-Quebec's 735,000 volt electric power transmission system was the first in the world to be designed, built and operated at an alternating-current voltage above 700 kV. This development extended the limits of long-distance transmission of electrical energy. On 29 November 1965 the first 735 kV line was inaugurated. Power was transmitted from the Manicouagan-Outardes hydro-electric generating complex to Montreal, a distance of 600 km.

Established 1965 the Orroral Valley Station, as well as the Honeysuckle Creek (1967) and Tidbinbilla (1965) sites supported NASA’s Deep Space Network, Manned Space Flight Network, and Spacecraft Tracking and Data Acquisition Network. The stations played a key role in supporting the Apollo 11 moon landing, with the Honeysuckle Creek facility providing the first historic pictures of man walking on the moon on July 20, 1969 (July 21st in Australia), as well as providing voice and telemetry contact with the lunar module.
