The Model ZB1 headboard is used in overhead line construction for OPGW cables, which combine the functions of grounding and fiber optic communication. During installation, OPGW cables are prone to twisting due to their stranded construction and the tension applied. The anti-twisting headboard counteracts this by stabilizing the cable and preventing rotation, which could damage the optical fibers inside.
The device is mounted at the pulling head of the cable, with counterweights spaced to ensure continuous anti-twist action as the cable passes through pulleys and tensioners. This setup is essential for maintaining the integrity of the cable throughout the installation process.
