ABB Successfully Tests Ultrahigh Voltage Transformer, Key for Power Superhighways
New transformer to be used on world's longest power transmission link in China
ABB developed the 800-kilovolt transformer within one year of winning a major order to equip the ultrahigh-voltage direct current (UHVDC) transmission corridor from the Xiangjiaba hydropower plant in western China to Shanghai, 2,000 kilometers to the east. It is the world's highest-voltage power link and will have a record capacity of 6,400 megawatts, capable of supplying about 31 million people.
The depth of utility lines vary, therefore EVERYTIME digging is required, even for small projects, a call to 811 is necessary. Failure to call before digging results in nearly 700,000 underground utility damages each year (src: Common Ground Alliance). Now, clearly marking underground utility lines is easy and affordable with Almetek's new Mini Curb markers.
