HVDC transmission is becoming increasingly popular for long-distance power transfer due to its superior efficiency and lower line losses. The shift to HVDC requires specialized equipment for both overhead and underground projects. Ningbo Changshi provides a range of stringing and tensioning equipment that is designed to handle the specific characteristics of the high-voltage conductors used in these large-scale HVDC projects. Our machinery is capable of managing the high tension and precise control necessary for the safe and efficient installation of HVDC lines, which are critical for connecting remote power sources to urban centers.
