What is UHV, literally understood as a particularly high voltage, how high is it?The voltage is divided into five categories: low voltage, medium voltage, high voltage, ultra-high voltage, and ultra-high voltage. Low voltage: 220V, 380V;Medium voltage: 10kv, 35kv, high voltage 110kv, 220kv;330kv, ultra-high voltage: 500kv, 750kv;UHV: 1000kV, DC 800kV.
Why build UHV?Electricity will be lost in the process of transportation, China's vast land, the electricity used by the common people, need ultra-long-distance, and ultra-large-scale transmission, and finally converted to low voltage can be used. To put it simply, the higher the voltage, the higher the transmission efficiency, and the lower the transmission loss, so the construction of UHV can save more energy.
