Jean-Jacques Archambault was a Quebec engineer, died December 23, 2001. He worked at Hydro-Québec and is known for his work on the 735kV electric transmission technology in the early 1960s.

735-kV transmission line[edit]

Shortly after being hired as a planner at Hydro-Québec he showed interest in the possibility of 735 kV transmission. With the highest operational voltage elsewhere being 525 kV[1][2] many American specialists affirmed that a 735-kV line was impossible to develop, but the Commission hydroélectrique de Québec approved his idea and launched a project to install a transmission line between Montreal and the Manicouagan-Outardes complex.[3] The 735-kV technology was put in service on 29 November 1965,[1] and described as the technological innovation of the 20th century for Quebec by the Ordre des ingénieurs du Québec.[1]

The Eastern Canada Council of the Institute of Electrical and Electronics Engineers gives out the Jean-Jacques Archambault Award of Merit in his honour, An amphitheatre in the Hydro-Québec Building in Montreal is also named for him.

In 2005, Hydro-Québec received an IEEE Milestone award for the technology.[4]
