Today, in order to provide electric power to different regions, the production, transmission and distribution of electricity are of great importance, and with the daily increase in the consumption of electric energy, the production and transmission of greater amounts of electric power is needed. As a result, at the transmission levels, new transmission lines must be established, which is very expensive and sometimes impossible due to the lack of sufficient privacy. Therefore, the solution of using the current existing lines and upgrading its voltage or current is provided, which is a solution to increase the capacity of the lines, greatly reduce the costs and solve the line privacy issues. The purpose of upgrading the voltage and current is that the existing tower can withstand higher voltage and current with the least changes in insulation and air distances and the tower structure and efforts to maintain the current structure and distances, thus increasing its transmission capacity several times. These redesigned lines with more precision, with reduced lateral dimensions (tower height, tower width, and span width) are called compact lines compared to existing old lines with the same voltage class. Some of the principles of compression are strengthening or replacing the insulator and using polymer and composite insulators, bundling of conductors, arrangement of phases, increasing the tension of the conductor and restraining the movement of the conductor. In this report, the voltage upgrade of the 132 to 230 kV line has been implemented by eva‎luating the initial line and using the solutions to solve the problems of the line for the upgrade, using the two solutions of the tower arm and the V insulator, and finally, the solutions are electrical, mechanical and economic have also been compared.
