Hydro-Québec PROJECT NEWS Spring 2019 Start of work to rebuild the 120-kV lines between the Vignan, Templeton and Interconnexion- Maclaren substations Hydro-Québec is set to rebuild the 120-kV transmission lines in the Gatineau area. These lines are located between the Vignan substation on Boulevard Gréber and the Interconnexion-Maclaren in the Masson-Angers sector. The lines will be dismantled and rebuilt on steel towers over a distance of close to 25 km. The work will be carried out by a specialized contractor. Dismantling and reconstruction are scheduled to take place from April 2019 to July 2020. The project is part of the company’s ongoing efforts to maintain and improve service quality. Project description 1- Dismantling of the line 2- Construction of the new • Preparatory work transmission line on steel towers • Installation of wooden H-frames and conductor covers • Foundations installed • Conductors, cables and hardware removed • Towers assembled on the ground, • Existing towers and foundations removed then erected using a boom truck • Conductors, cables and hardware The dismantledVal-des-Monts, M equipment will be sent to specialized installed recycling Cantley,sites M in compliance with current laws and regulations. Work areas will be restored as the work progresses. The southern line in Section 1 will continue to deliver electricity until the new line is commissioned. Note: Between the Vignan substation tap and the Produits-Forestiers-Résolu substation, as well as between the Erco Mondial tap and the Interconnexion-Maclaren substation, only the conductors and equipment Les Collines-de-l'Outaouais (MRC) will be replaced, since the existing towers will be retained.
