UTS Coordination of Tower, Conductor and Insulator

07/24/2011 1:01 PM

what is the reference from where Ultimate tensile strength of a conductor is selected ?

and how the UTS coordination maintained between gantry structure(Tower legs, tower member and beam), insulator string and conductor ?

Different materials have different UTS, Machinery handbook is a good investment to understand that.

conductor selection and tower design must be complex design issue and I don't think any one can have a short answer for that, lot of variables involved, and to me it looks like iterative process. more is tower span thicker will be conductor required, and thicker conductor means stronger tower is required. differential altitude may also matter in design considerations and so on.

Based upon your consistently choosing the wrong design criteria for your series of questions you should consider declining any further involvement in this project. From Wikipedia ..."Ultimate Tensile Strength (UTS) is not used in the design of ductile static members because design practices dictate the use of the yield stress..." For the reasons Mr. Semwal has already stated, this is not an exercise in "Handbook Engineering".

Transmission line design, which encompasses conductor sizing and material, insulator string, tower and footing selection, engineering and design is a multidisciplinary subject involving civil, mechanical and electrical expertise. There are Consulting Engineering firms that specialize in this type of work, investigate them and hire local professionals to do the job properly. The advice you receive here (including this posting) is worth every penny you paid for it.
