EVOLUTION OF. THE DESIGN FOR THE 735 KV
TRANSMISSION LINES OF HYDRO-QUEBEC
(1980)Abstract
Several modifications, some of which are considered innovations, were made in the design of the new
735 kV lines of the Hydro-Quebec network. These modifications have dealt with: the reduction of electrical
clearances and the distance between phases; the insulation systems; the establishment of atmospheric loads; the
basic principles of line design viewed as a system ; the design of a spacer-damper to control the oscillqtion
problems of bundled conductors ; the utilization of guyed towers for the first two lines of the James Bay network
and of chainette type structures for certain sections of the other three lines and the design, for the northern regions,
of foundations and guy anchors.
