Improved Performance of Electric Transmission Concrete Poles for National Integrated Power Project (NIPP) in Nigeria

Abstract

This paper deals with the testing of electric transmission concrete poles. The Dillon (precision Electronic Dynamometer family) used was inspected and was certified to be in perfect condition before testing commenced. 1000 concrete poles were tested arranged in batches of 400 and 300poles. These poles were arranged in such a manner that the markings, serial numbers e.t.c., with pole positions are easily seen. Also the poles were stacked in such a manner that any pole selected for testing was easily drawn out.  All poles tested satisfied the standard acceptance criteria to withstand any concrete pole failure for the National Integrated Power Project (NIPP) electrification purpose based on the experimental validations carried out for different actual applied loads plotted again the pole deflection.
