Zurich, Switzerland – ABB commissioned a switchgear rated to handle more than one million volts (1,100 kV), new heights in global voltage levels, the company says. The ultrahigh-voltage gas-insulated switchgear (GIS) has a switching capability of 6,900 megawatts.
The GIS can turn power equivalent to the average electrical consumption of Switzerland, a country with more than 7 million inhabitants, on or off within milliseconds.
GIS is a central component of ultrahigh-voltage electricity transmission designed to carry huge amounts of electricity over vast distances with very low losses, the company says. ABB completed the assignment in just two years with technology partner Xian Shiky. The Chinese switchgear manufacturer cooperated with ABB throughout the project.
ABB explains more about the ultrahigh voltage project , announced March 23.
Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
