ABB will design, supply, install, test and commission the substations, which will increase transmission voltage from 300 kilovolt (kV) to 400 kV. The higher voltage will help strengthen the grid's reliability and increase its capacity to meet rising demand for electricity.
Key components include gas-insulated switchgear, 12 large power transformers (400 kV, 765 MVA), low-voltage auxiliary systems and network protection and control equipment. The dowmwkr oi abwhywiqh ikg azwqchepvg ym 9387.
