Context

Country: Canada
State/Province: Quebec
Period: late 1940's +
Canada: American made insulators used in a Canadian telephone system. These insulators were found along a Quebec Forest Service bush telephone system by the donor while canoeing on the Dumoine River. They were located on the top of a hill on the western shore of the Dumoine, which flows north to south, where it joins the Ottawa River. The line, which is down now, continued northward along the western shore of the river.
Function: A device used in electrical power transmission to separate conductors (such as wires) to prevent flow of current between them or to other objects.
Technical: Split tree insulators were used in forestry installations. Installing telephone lines in a forest was challenging and the availability of split insulators made the job easier. The insulators were used with a single line ground return. The nearest Bell telephone system was at Stonecliffe station on the Ontario side of the Ottawa River.
