This paper presents the status quo and tendency of development of the conductors for the 500 kV large capacity transmission lines used in the Three Gorges Project. The main contents of the research include six new conductors of different type and size, test and inspection of overhead conductors and set up of aluminium alloy conductor factories. This paper describes in detail the raw materials for the six new type conductors including electric aluminium conductor, high strength aluminium alloy conductor, aluminium clad steel wire, high strength galvanisel steel wire and super high strength galvanised steel wire; process and equipment needed including aluminium(alumnus alloy) continuous casting and rolling, aluminium continuous extrusion, continuous wire drawing, cold press weld and wire stranding; and test technique and condition of overhead conductors. It also presents the economic and social benefits to be brought about by the newly developed conductors as well as the promotion to and influence on the Wire and Cable Industry in China by the new conductors.
