Power transmission line is a kind of electrical energy transmission installation that connects power plants, substations and electrical equipment. It is divided into overhead lines and cable lines. The high-voltage transmission line is the main artery of the power industry, and is an important part of power fragmentation. This time, we will introduce overhead transmission lines.
Power lines are divided into transmission (transmission) lines and distribution lines. The line that the power plant sends to the power load center to guarantee power and the connection line between the pieces of power are called transmission (transmission) lines, and the line that the power load center distributes power to each power user is called the distribution line.
Power lines are divided into high-voltage, high-voltage, ultra-high-voltage, and ultra-high-voltage lines according to voltage level. Voltage levels below 1kV are high voltage lines, 10kV and above are high voltage lines, 500kV and above are extra high voltage lines, and 750kV and above are extra high voltage lines.
Transmission lines are divided into overhead transmission lines and cable transmission lines according to the line erection information. Transmission lines are divided into AC and DC lines according to the nature of the current. Overhead transmission lines are divided into single loop, double loop, and multiple circuit roads according to the number of circuits on the tower.
