735-kV transmission line
Shortly after being hired as a planner at Hydro-Québec he showed interest in the 735-kV innovative idea. In 1962, while many American specialists affirmed that a 735-kV line was impossible to develop, the Commission hydroélectrique de Québec approved his idea and launched a project to install a transmission line between Montreal and the Manicouagan-Outardes complex. The 735-kV technology was described as the technological innovation of the 20th century for Quebec by the Ordre des ingénieurs du Québec.
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.
