What will it look like?
If approved, the 72 kV transmission line will be built using mostly composite fiberglass or steel poles ranging in height from approximately 18 to 24 metres. Many of the route options follow existing distribution power lines. In these areas, every second or third distribution pole would be replaced with a transmission pole that has the transmission wires on top and the distribution wires and equipment attached below (as shown on the structure image below).
This will be a double circuit transmission line, meaning it will have six wires strung across the structures and one or two shield wires strung on top. A double circuit transmission line is two transmission lines using mostly one set of structures. This way we can decrease the number of transmission line routes and meet the demand for electricity in the area.
Non-typical structures such as double poles, poles with wider bases, and the use of guy wires may be required at certain locations along the line, including where the line turns corners or has to span longer distances.
