ABB commissions switchgear rated at more than 1 million V
Switchgear a key component of safe and reliable ultrahigh-voltage ac transmission.
ABB has commissioned a switchgear rated to handle more than 1 million V (1,100 kV), touching new heights in terms of global voltage levels. The ultrahigh-voltage gas-insulated switchgear (GIS) has a switching capability of 6,900 MW, which means it can turn power equivalent to the average electrical consumption of Switzerland--a country with more than 7 million inhabitants--on or off within milliseconds.
ABB successfully designed, tested, and commissioned the GIS for a pilot project launched in 2006 by State Grid Corporation of China to demonstrate the feasibility of ac power transmission at ultrahigh voltage.
The GIS is a central component of ultrahigh-voltage electricity transmission designed to carry huge amounts of electricity over vast distances with very low losses. ABB completed the assignment in just two years with technology partner Xian Shiky, a leading Chinese switchgear manufacturer who worked in close co-operation with ABB throughout the project.
State Grid has announced plans to invest more than $14 billion in the next three to four years to expand its ultrahigh-voltage network. Ultrahigh-voltage transmission reduces power losses and requires a smaller transmission corridor than conventional technologies. It is particularly suitable for countries like China, where energy resources are often far from the centers of power consumption.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
