Sag and Tension Calculations - Refinements and ...

Unlike traditional sag-tension programs that rely on a database to define properties for the selected conductor, these values are calculated by an auxiliary program. Developed by Trimble, this program works with the sag-tension program. The calculated properties associated with the selected conductor are used in analysis calculations and include:

Presently, power-based equations remain the principal method for designers to size mills and estimate the power requirement for comminution circuits. The technique is simple and it relies on the design to specify a feed and product size plus a hardness index to produce a specific energy value (kWh/t).

Calculation of Sag & Tension in Transmission Line - for Level ...

The sag at OA and OB is expressed by the equations. The tension A and B are given by. The maximum tension will occur at B since (l-x) is greater than x as seen in the figure above. Vertical reaction at the higher support – w.(l-x) Vertical reaction at lower support – w.x. For calculation, it is assumed that the AOB is the parabola. But,
