What Is A High-Voltage Cable?
Ultra-high voltage transmission refers to the use of 500 kV-1000 kV voltage levels to transmit electricity.
If the 220 kV transmission index is 100%, the relative investment per kilometer of UHV transmission, the relative cost per kilowatt-hour electricity transmission a hundred kilometers and the consumption of metal materials, и т.п., have been significantly reduced, and the line corridor utilization rate has been significantly improved.
In our daily lives, we can often see the overhead ultra-high voltage transmission project, whether we have thought about the question: why can not be like the city underground cable, high-voltage power lines all buried underground?
