In the sag formula, what does 'D' represent?

In the sag formula, 'D' represents the sag in inches. This is the vertical distance that a cable or wire sags due to its own weight when it is installed between two supports. Understanding this component is crucial for linemen as it helps determine how much a line will droop under load, which is important for both safety and design. Accurate sag calculations ensure that wires are installed with the correct clearance above the ground and other structures, preventing potential hazards and ensuring compliance with electrical codes.

The context of understanding 'D' further emphasizes why it's not associated with distance, diameter, or depth, which relate to other aspects of cable installation or specifications but not specifically to the measurement of sag itself.
