Cranbrook 60kV Energized Rebuild and Reconductor
Client: BC Transmission Corp
Owner: BC Transmission Corp
Project Status: Completed
Location: Cranbrook BC
Category: Energized services
Replace structures and reconductor, 4.6km of 60kV transmission line without an outage on the circuit. 90% of the structures required upgrading including tangents, 90 degree deadends and long span crossings. The conductor was also upgraded to increase capacity.
The 60kv transmission and the 12kv underbuild distribution circuits both had to remain energized during work so there would be no disruption to the community or businesses in the area
This was the first time 60kV energized reconductoring was successfully completed in in Canada and the first time Transmission Energized stringing took place on the BC Hydro system.
Specialized Work Methods:
The linemaster Robotic arm played a critical role along with unique liveline stringing techniques created specifically for this project to provide the limits of approach required to install the new structures and conductor in an energized stateSlider popup
