Ground clearance is directly affected by the sag of the conductor, which is the downward curve of the line between two support structures. The factors that influence this sag and, therefore, the ground clearance are:

• Conductor Weight: The inherent weight of the conductor itself.

• Tension: The pulling force applied to the conductor. Higher tension results in less sag.

• Temperature: As the conductor heats up (due to electrical current or ambient temperature), it expands and elongates, which increases the sag.

• Environmental Loads: Heavy loads like ice and snow add weight, increasing sag. Strong winds can cause the conductor to swing, reducing its horizontal clearance.

Our OHTL wire cable conductor tension stringing equipment is engineered to precisely control the tension and sag during installation, ensuring that the ground clearance remains within the required safety standards under all operating and environmental conditions.
