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, etc., 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?
