|Transmission Line Structure using Steel Pole|
Steel poles is fast becoming the pole of choice in construction of power lines. Most of the replacement of wooden poles have been to steel poles.
Steel poles has a distinct advantage over wood poles, primarily its durability and longer life span (if properly treated, like galvanizing).
This article is basically a guide on the standards and codes used in the design of steel poles. The standards presented herein are that of the US Rural Utilities Services.
Codes, standards, or other documents referred to in this specification shall be considered as part of its specification. The following codes and standards are referenced when designing and fabricating steel poles to be used as transmission or distribution poles in the areas within the US Rural Utilities Services.
