British Columbia, Canada

     
 
 
Kemess Mines Inc., a subsidiary of Royal Oak Mines, developed a gold and copper mine in the northwest part of British Columbia, just south of the Yukon border. Studies determined that the optimum source for the operation of the mine would be electric power delivered by a transmission line from the nearest point on the BC Hydro system, some 380 km southeast of the mine site.

Teshmont was selected as the transmission line engineer to complete the work over a short implementation schedule. The timing from initial studies to completion of line construction was 22 months.

The transmission line was designed with one “ELGIN” AASC conductor per phase with a phase spacing of 6.75 metres. The tangent structures were guyed “Y” self weathering tubular steel, light and medium angle structures were flying angle 3 pole guyed tubular steel, and the heavy angle and dead end/terminal structures were 3 pole guyed tubular steel with strain insulators. The majority of the foundations for the structure guys and masts were of the steel grillage and timber mat type. The clearing and construction activities were carried out in compliance with the Forest Practices Code of British Columbia.
