Longshan 110 kV Transmission & Transformation Project
110 kVSUNENG supplied selected power transmission and distribution products and components for the Longshan station and line works.
Project context.
The Longshan project connects a new outdoor 110 kV substation in Huangcun Town, Hukou County, to the surrounding Jiujiang network. The completed station contains one 50 MVA main transformer and two 110 kV outgoing bays.
The electrical scope covers the Hailong and Shuanglong connections, combining overhead conductors, lattice towers, steel poles and underground cable. Construction completion is recorded as 26 May 2026. The Hongshan section and the Hongguang 220 kV bay were not energized in the documented phase and are excluded from the completed scope shown here.
