Hydro-Quebec's Experience with the Design and Construction of 1500 KM of 735 KV Chainette Transmission Lines

This paper deals with the design and construction experience that Hydro-Quebec acquired with 1500 km of 735 kV chainette lines already in service. The design features of this type of tower are discussed as well as the parameters of the chainette tower used on James Bay lines. Through the paper, the construction of the chainette tower is compared to the guyed V tower and the productivities of construction crews are discussed. Comparative material and construction costs are also detailed in the paper.
