High voltage wire usually refer to transmission lines that transmit voltage above 10kV. According to GB/T 2900.50-2008, defined in 2.1, high voltage usually does not contain 1000V. The voltage levels of China’s domestic high-voltage transmission lines are generally divided into 35kV, 110kV, 220kV, 330kV, 500kV and 750kV.

There are a lot of people wondering why high voltage wire are all three wires. In fact, in China, three-phase and three-wire system is often used for high-voltage AC power transmission in the power system, so the high-voltage line has three wires. Conversely, if the high-voltage DC power transmission adopts two-phase electricity, there will be two wires.
