What exactly is a "Cable Sagging Machine" and what is its primary purpose in power line construction?
2025-07-21
A Cable Sagging Machine, often referred to as a tension stringing machine or conductor tensioner, is specialized equipment used in the installation and maintenance of overhead transmission lines (OHTL) and sometimes underground cables. Its primary purpose is to precisely control the tension of wire cables and conductors during the stringing process, ensuring they are installed with the correct "sag" according to engineering specifications. This precise tensioning is critical for maintaining adequate clearance from the ground and other objects, preventing excessive stress on towers, and optimizing the electrical performance of the line.
