Wanfu 110 kV Transmission & Transformation Project
110 kVSUNENG supplied selected power transmission and distribution products and components for the Wanfu substation, connecting bays and line works.
Project context.
The Wanfu project serves the Wuning Industrial Park area in Xinning Town, Wuning County. The completed outdoor substation has two 50 MVA main transformers, outdoor 110 kV HGIS equipment and three outgoing 110 kV bays.
Connections comprise Ningwan I, Ningwan II and Wannan, with a combined route length of 15.252 km. The works also connect two 110 kV bays at Xinning 220 kV substation, including one existing spare bay brought into use, and a new 110 kV bay at Nanshi. The figures below use the completed installation values.
