ABB wins $25 million power equipment order

ABB has recently won a $25 million contract to deliver 500 kV gas-insulated switchgear (GIS) to China, the latest in a series of orders designed to improve power supply.

ABB announced recently that it has won a $25 million contract to deliver 500 kV gas-insulated switchgear (GIS) to China. The contract is said to be the latest in a series of orders designed to improve power supply.

The GIS will be installed in converter stations that will support the 1,100 kilometre-long, high-voltage direct current (HVDC) power line which ABB is building to connect the Three Gorges power plant with Shanghai.

“Our GIS technology is a robust and space-saving solution specifically designed for such high power ratings,” said Peter Smits, head of ABB’s Power Technologies division. “The power link, using our HVDC technology, will secure reliable and energy-efficient power transmission for consumers in Shanghai.”

China’s State Grid Corporation awarded contracts to Xian High Voltage Switchgear Company and New Northeast Electric (Shenyang) High Voltage Switchgear Company to supply 500 kV GIS substations for converter stations, which are needed to connect the HVDC power line to the grid. ABB received subcontracts from both to deliver the main part of the stations. The contracts include delivery within 18 months.

An ABB-built, 940-kilometre long HVDC link commissioned this June connects the Three Gorges power plant with Guangdong province. According to ABB, new hydropower plants are being built in Central China to meet surging demand for electricity in the rapidly growing eastern coastal regions.
