Abridgment of rural line construction in Ontario

This is a description of a large rural distribution system with some 4800 mi. of primary circuit. The history of the system is given from its inception as a few scattered extensions of town systems up to the present. The paper covers in detail the various forms of construction in use with the reason for their adoption. Comparison of lines are given with various span lengths and voltages. An 8000/4600-volt system has been adopted for part of the district and it is described in detail. In one area, a considable quantity of underground cable has been installed at a cost for single-phase not much greater than for an overhead line.
