In recent years, the actively developed research works of monitoring and evaluating the power transmission line and preventing and reducing disasters can not leave the building and simulation analysis of a tower line system.

The transmission line tower wire system mainly comprises a tower, a lead, a ground wire, an insulator string, a spacer, a wire clamp and other hardware fittings.
The tower is one of the core components of a tower line system of a power transmission line, and is used for supporting a lead and a ground wire and ensuring a certain safety distance between the lead and the lead, between the lead and the ground wire, between the lead and the tower, between the lead and the ground, a building, a power line, a communication line and other spanning objects or adjacent objects. The tower can be divided into a tangent tower, a corner tower and the like. The lead is another core component in a tower line system of the power transmission line, is mainly used for conducting current and transmitting electric energy and is a current-carrying main body of the line. The ground wire is also called a lightning conductor and has the function of leading lightning current into the ground so as to protect line equipment from being insulated and prevent lightning from being damaged. The ground wires are usually suspended on the top of the tower, the number of the ground wires depends on the voltage class, the form of the tower and the lightning activity, and single ground wires or double ground wires can be generally adopted. The insulator string has the function of supporting the lead in the power transmission line tower and line system and keeping the insulation distance between the lead and the tower.
The establishment of the power transmission line tower line system is the basis and key for developing power transmission line monitoring evaluation and disaster prevention and reduction researches, but the establishment of the tower line system in most of the existing researches is not realized in a systematic method and is realized in a multi-purpose manual mode, so that the working efficiency of researchers is reduced, and the method for automatically generating the tower line system is required to be established, so that the working time can be greatly saved, and the efficiency is improved.
