Sag-Tension-Creep Polynomials

[PoleGuy]

Does anyone know a good resource (publications, website, etc) that provides a comprehensive list of the polynomial equations for various conductors used in T&D? Trying to put together some in-house tools for sag-tension-creep determination for a project we have.

Thanks in advance for any input!

The makers of PLS-CADD mention that polynomial the models they supply came from publicly available sources.

The Aluminum Association has stress/strain graphs of various popular conductors and the polynomials you are looking for are on those graphs.

go to

http://www.aluminum.org/resources/electrical-faqs-and-handbooks/electrical

and look for the stress strain creep curves for aluminum overhead electrical conductors at the bottom of the page.

The PLS CADD website has a big collection of wire files available for download. The wire files have the polynomial coefficients in them.
