Red Bull Track Line Modification and Salvage ( PQ4-230kV )
Project Status: Complete
Location: Qu'Appelle Valley near Bethune, SK
Length: 1 Month
Category: Energized services
The project consisted of modifying the PQ4 230 kV transmission line crossing, near Pasqua, Sk., to accommodate a new Canadian Pacific (CP) Rail spur line (Red Bull Track) by relocating a galvanized steel H-Frame structure, approximately 30m from its previous location. The new structure was directly embedded in steel casings, which were supplied as part of the project. The PQ4 line remained energized during construction and barehand techniques were used.
- The PQ4 Circuit feeds the K+S Potash Mine and Enbridge Bethune Pumping Station; therefore, all work was completed with the 230 kV circuit energized.
- The installation of steel casings, each 12m X 1.2m, was completed using a Vibratory Hammer between 230 kV energized phases. Stringent work procedures, which adhered to electrical clearances were implemented to ensure safety.
- Work was conducted on CP rail Right of Way (ROW) and required compliance with CP rail’s guidelines and limitations.
