Electric power is an energy source using electric energy as power. In the 70 s of the 19 th century, the invention and application of electric power opened up the second industrialized climax, and electric power transmission equipment, the most common electric power transmission equipment, was a transmission line, which is an important member for realizing electric power transmission and overall deployment.

The electric energy transmission refers to a mode of transmitting electric energy from one place to another place by a power plant or a power supply, and because the electric energy transmission in the early technology is immature, direct current transmission is adopted, and the electric energy transmission gradually becomes alternating current transmission in the later period, the alternating current transmission has many advantages, the loss in the electric power transmission is reduced, and the speed and the transmission length are improved. In order to reduce the loss of electrical energy in the transmission line, only the voltage can be increased. The voltage is increased in the power station and then is reduced in the user area, so that the purpose of long-distance power transmission can be achieved under the condition of low loss. And only by using ac transmission, the voltage is changed. In 1888, power transmission began from a large ac power station at the riverside of time, london, designed by felnsti. The other uses the steel sheet copper core cable to send 1 ten thousand volts of alternating current to the transformer substation in the urban area with a distance of 10 kilometers, and then the alternating current is reduced to 2500 volts, and then the alternating current is sent to the secondary transformer of each block, and the alternating current is reduced to 100 volts for the illumination of users. Later, the pioneering san 100 watt three-phase ac generator was produced in 1889 by pluvio-pluviosides and popularized in germany and the united states. The superiority of high voltage ac transmission has been successfully demonstrated. And is rapidly popularized all over the world.
