The Cable Tension Machine is a core equipment for “tension stringing construction” in overhead transmission line projects. Used in conjunction with cable traction machines, its primary function is to apply constant and controllable tension to the cable during the installation process, ensuring the cable remains in a taut state (to prevent damage from grounding or tangling due to slack).

Meanwhile, it collaborates with traction machines to enable the cable to move smoothly along the pulleys on transmission towers, serving as a key piece of equipment for guaranteeing the erection quality of large-cross-section and high-voltage-grade cables.
