The second transformer of Ba Don 220kV substation
The project is invested by the National Power Transmission Corporation (EVNNPT), managed by CPMB, and operated by Power Transmission Company 2. This is an energy project, grade I, group C, with a total investment of more than VND 77 billion.
The project is implemented in the precinct of the existing 220kV substation with the scale of installing an additional 220kV - 125MVA transformer in the backup position, increasing the capacity of the substation to 250MVA. On the 220kV side, complete from the diagram "One busbar" to the diagram "Two busbar systems with contact breaker", this stage installs equipment for 1 main bay of AT1 transformer, 1 equipment bay for communication bay; additional 2nd busbar switch for 3 existing bay; additional lightning protection valve, voltage transformer for the 2nd busbar (C21 busbar). On the 110kV side, this phase installs equipment for 1 main bay of the AT1 transformer.
The project completion of installing the second transformer of the Ba Don 220kV substation is aimed at enhancing the power supply capacity for socio-economic development in Quang Binh province and surrounding areas, reducing load and avoiding overload for existing transformers and 110kV power lines in the area, releasing the capacity of renewable energy sources in the region to the national electricity system.
