The 132 wooden H-frames will be replaced by about 38 steel towers.


Hydro-Québec plans to rebuild two 120-kV* transmission lines on wooden H-frames, between the Arthabaska substation tap and Bois-Francs substation in Victoriaville. These two lines will be dismantled and replaced with a new 10-km line on steel frames. This project will meet the growing electricity demand and ensure the reliability and long-term operability of the electrical system for all customers supplied by Bois-Francs substation.

Construction work is scheduled for spring of 2018 and commissioning is slated for the fall of 2018.

* kV = kilovolt, or 1,000 volts.
