Crossing the St. Lawrence with unstressed cable lengths

In designing and building the 132 kv transmission line crossing between Kanawake and LaSalle, Quebec, on the St. Lawrence River, the unstressed cable lengths were calculated, measured, and cut to be continuous over 3 spans. The calculated unstressed lengths were measured in the field while the cable was being erected, without delaying the stringing and without necessitating rehandling of the cable.
