Hi Engineers,
any suggestion on what formula to use to create a catenary given the sag and span of conductors?
Cheers!

Another question/request,i wonder if the simple catenary can be designed using MSExcel given the sag and span for level and un-level condition?
thanks

This is an excellent reference.

If you are designing a line, you would probably be better to hire someone with experience in this area, as there is a lot to know.

RE: Catenary
You need these conductor characteristics if you need to find the sag-tension at a different loading/temperature condition. For instance, you might want to calculate the stringing sag and tension at 60°F to get a sag at 120° final with wind. For this, an Excel spreadsheet may not be feasible because the calcuations are pretty complex, especially for a composite conductor like ACSR.
