Professional Answer: For 220 kV overhead transmission line projects, a 180 kN stringing machine offers a significant advantage in efficiency and safety. The high pulling force is essential for stringing large, heavy conductors over long spans and challenging terrains, which are common in 220 kV projects. This capacity allows for the stringing of multiple bundled conductors simultaneously, reducing project timelines and operational costs. Furthermore, our machines are equipped with precise tension control and automatic overload protection systems, ensuring the integrity of the conductor and enhancing worker safety throughout the process.
