After this span the overhead line runs westward to Vancouver Island Terminal near the town of Duncan.
The stations Vancouver Island Terminal and Arnott Substation were designed and delivered by Swedish company ASEA (later ABB).
This pole used thyristor valves for its static inverters and operated at a voltage of 280 kV with a rating of 370 megawatts.
submarine cable for three-phase alternating current has been constructed between the Canadian mainland and Vancouver Island.
In the 2005 hearings for the new 230kV circuit the HVDC systems were reported to be at the end of their service life and are not considered to be reliable.
After this point it runs on wooden poles together with a single-circuit three-phase AC line until 49°2′25″N 123°4′32″W / 49.04028°N 123.07556°W / 49.04028; -123.07556 (Metallic Return Cable Terminal).
It is connected with Vancouver Island Terminal by an overhead line with two conductors, which is installed on wooden poles.
