Answer: When using a turnbuckle for overhead power line cables, the process involves a few critical steps to ensure safety and long-term tension stability. First, ensure the turnbuckle's Working Load Limit (WLL) is appropriate for the application. You must also select the correct end fittings (such as eye-and-eye or jaw-and-jaw) that are compatible with the adjacent hardware. After attaching the turnbuckle, adjust the tension by rotating the body of the turnbuckle. This causes the opposing right-hand and left-hand threads to pull the end fittings closer, tightening the cable. Once the desired tension is achieved, it is crucial to secure the turnbuckle with a locking mechanism, such as lock nuts or safety wire, to prevent loosening from vibration or environmental factors.
