Abstract

Assessment of the health status of wooden posts installed in the neighborhoods of Mavalane, Hulene and Polana Caniço, on the outskirts of Maputo city The present work presents the results of the health status of poles in service in the Polana Caniço, Hulene and Mavalane neighborhoods in the outskirts of Maputo city, resulting from a study carried out to assess the influence of years in service on the health status of poles as well as test a pole inspection technique in service; thus contributing to the development of a technique for inspection of wooden posts. This is an area with about 1500 wooden poles currently in service in which a systematic analysis of these poles in service was carried out, with 160 wooden poles being inspected for transmission of low voltage energy, As a result of the inspection, it was found that 70% of the wooden posts in service registered some type of damage. In general, the combination of mechanical/biological damage was the most frequent, Of the poles installed 22 years ago in the neighborhoods of Mavalane and Hulene suffered the greatest attack by deteriorating agents, 35% of which with mechanical/biological damage. Poles in service for 15 years had 72% of poles attacked, with mechanical/biological damage being the most evident. Thus, it is recommended to implement inspection and maintenance programs as well as immediate curative treatments to all usable posts; that are low cost, efficient and feasible to apply,
