Professional Answer: At Ningbo Changshi, we prioritize conductor integrity. Our 180 kN stringing machines utilize wear-proof bullwheels with specialized linings to minimize friction and prevent surface damage. We also adhere to the tension stringing method, which keeps the conductor elevated off the ground and away from obstacles, preventing scratches and abrasions. Our equipment includes real-time tension monitoring and load-limiting devices to ensure the pulling force never exceeds safe limits, protecting the conductor from overstressing.
