A telecommunication pole is one of the most important network infrastructures used to carry overhead telecommunication lines.
In wooden poles, as support of communication lines, the following circumstances are present:
The wood, when the antiseptic efficiency of the preservative treatment has decreased below the threshold, is subjected to the attack of biological agents that cause its destruction.
Healthy wood of poles must preserve the mechanical strength that line security requires.
The heavy expense of wooden poles as well as the cost of reposition works with new poles, recommends conserve and extend as much as possible, with in the wide security margins for workers, poles lifetime; this can be achieved by means of different systems as reimpregnation, lowering, recover and reclassification.
Other material used, in common utility poles is concrete. These poles are planted into the ground, but in some cases, they lean or overturn by forces such as strong wind. This phenomenon is mainly due to a foundation failure. This Recommendation deals with integrity testing for telecommunication pole's foundation.
