White porcelain insulators are used to support the 50,000-volt Shawinigan line, and are of a recent design.
The pins for the Shawinigan line were boiled in stearic acid.
Thirty thousand horse-power is used in Shawinigan itself for the production of aluminum and carbide.
At this sub-station the 85-mile transmission line from the generating plant at Shawinigan Falls terminates.
Ten years ago Shawinigan Falls was an almost unheard-of point in the wilds of Canada.
