Electrical Tower Calculation

Dear,

You may have to refer to the Design hand book for the same.

You have to consider the SAG permissible for particular size of conductor.

Then Bending stresses on the Tower - Max. Wind Velocity / etc.. should be consider

Then, accordingly, Foundation design shall be finalised

This should help...

[PDF] Sag-tension Calculations

It must be that time of year again when finals are coming up

A couple of replies referred to sag-tension tables. Check them. They probably use the catenary calculations/equations. You probably need such data as sag, weight per foot of the cable (bare and iced), the span, and maybe others.

I used to design single shaft towers for high voltage electric cables. In a tangent (straight thru) suspension connection, the load on the support is transverse (wind, wind on iced cable, etc) and vertical (cable weight, ice, etc. When there is a line angle, you will also get load from the line tension. There is much more involved, of course. We usually got the tension info from the electric utility, so did not really do these calculations.
