Investigation into the causes of electric transmission concrete pole failure

Abstract

Abstract The major causes of electric concrete pole failures has been highlighted in this paper and possible solutions suggested. The technique involves an on-site assessment and analysis of some factors that influence the design and manufacture of concrete pole commonly used for electrification purpose. Some major manufacturers in Niger State, Kwara State and Federal Capital Territory, Abuja, Nigeria were visited and interview conducted on their method of design and manufacture of electric transmission concrete pole. Site study of some major high-tension and low-tension electrification work was also carried out. Based on observation made anomalies in concrete pole manufacture were pointed out and solution proffered. Finally concrete pole suitable for electrification purpose was designed and constructed. A rig was constructed to test the strength of the pole, thereby determining their suitability for electrification work.
