Sag and tension calculations are a fundamental aspect of overhead line design, ensuring conductors maintain safe clearances and do not overstress the supporting structures. The calculation involves a detailed analysis of:

• Conductor Weight: The weight per unit length of the chosen conductor.

• Span Length: The distance between supporting poles.

• Working Tension: The tension on the conductor, which must remain within safe limits.

• Weather Conditions: Factors such as wind load and ice accumulation significantly impact sag and tension.

• Temperature Variations: Changes in temperature cause the conductor to expand and contract, directly affecting sag.

The classic catenary formula (s = wL^2 / 8T) provides a basis for this, where 's' is sag, 'w' is conductor weight per unit length, 'L' is the span length, and 'T' is the conductor tension. For more complex scenarios, specialized software and detailed sag-tension charts are used. We offer all the necessary tension and stringing equipment to manage these calculations and ensure precise conductor installation.
