In transmission line construction, any scratch, twist or deformation on the conductor surface can shorten the service life of the line and create hidden safety risks. In Saudi Arabia, with large conductor sizes, long spans and strong winds, poor tension control can easily lead to excessive friction in the stringing blocks, causing conductor surface damage and making sag control very difficult. This has been a common pain point for many local contractors.

To solve this problem, the project team decided to integrate HYDRAULIC TENSIONER SA-YZ50 units into their stringing system. During operation, the SA-YZ50 hydraulic tensioner provides a constant and adjustable tension throughout the entire stringing process. Even when crossing roads, valleys or other obstacles, the conductor sag can be kept within the designed range. This prevents the conductor from sagging too much or suddenly rebounding due to abrupt changes in tension.

In actual field use, the customer found that after introducing the Hydraulic Tensioner SA-YZ50, the conductor ran much more smoothly through the stringing blocks. Surface scratches and slight twisting were significantly reduced, and there was almost no need for rework or re-tensioning at the end of each section. Thanks to stable tension control, the final line appearance, sag consistency and the accuracy of hardware installation were all noticeably improved.

The site supervisor commented that, in the past, they relied heavily on operator experience and “feeling” to control tension, which put a lot of pressure on the crew and led to large quality variations. Now, with the SA-YZ50, tension control is based on measurable parameters and hydraulic control, not just experience. Quality is more stable, acceptance is easier, and inspection results are more consistent. The contractor plans to standardize the use of Hydraulic Tensioner SA-YZ50 on future projects in Saudi Arabia and neighboring countries.
