Designer of a Major Technological Breakthrough
When Hydro-Québec engineers were debating the technology to be used to transmit the enormous quantities of energy generated at the Manic-Outardes complex, Jean-Jacques Archambault, a young graduate of the École Polytechnique in Montréal, suggested a bold solution: 735-kV transmission lines, something never seen before. Archambault managed to convince his co-workers and Hydro-Québec management that this was the right option. The decision to use 735 kV as the transmission voltage gave rise to a host of technological innovations. Everything—circuit breakers, disconnectors, transformers and other equipment—had to be redesigned to transmit such large amounts of energy with a minimum of loss and noise. Experts from as far afield as Sweden, Germany, France and Italy cooperated in drawing up the plans and constructing the world's first 735-kV line. During the celebration of the 100th anniversary of engineering in Canada in 1987, this feat was recognized as one of the ten most important technological innovations of the 20th century.
