Shanggao Power Plant 500 kV Outgoing Project
500 kVSUNENG supplied selected electrical products and components for the Shanggao 500 kV outgoing project.
Project context.
The Shanggao outgoing project connects Yichun Power Plant, formerly known as Shanggao Power Plant, to Jinjiang 500 kV substation in Shanggao County, Jiangxi. The completed Yijin line runs for 30.863 km and includes 72 new towers, together with one additional 500 kV outgoing bay within Jinjiang substation.
Most of the route uses single-circuit construction. The final 0.113 km enters Jinjiang on a double-circuit terminal arrangement with one circuit installed. The route crosses the Jinjiang River and passes beneath the ±800 kV Binjin line. The photographs show tower foundations, steelwork connections, overhead spans and the station approach.
