High-voltage AC Transmission Lines Characteristics:

1) High reliability requirements for safe operation. Due to the large transmission capacity of high-voltage AC transmission lines, energy transmission lines, which are often the main power points and load centers, play a very important role in the power grid. Once a safety accident occurs, it will have a great impact on the economy.

2) The structural parameters of the line are high. High-voltage AC transmission lines have high towers, long insulator strings, many insulator pieces, and large tonnage. Not only is it difficult to repair after a collapse accident, but it also requires very high preparation for spare parts.

3) The operating parameters of the line are high. The rated voltage of high-voltage lines is relatively high, making the electric field intensity around charged objects higher.

4) The line is long and the geographical environment along the line is complex. High-voltage lines often pass through mountains and valleys, causing transportation difficulties and heavy maintenance workload.
