RESUMO

The purpose of this paper is the theoretical and experimental study of evaluation of timber deterioration in used poles in nets of electric energy. Basing on ample bibliographical reviews of climatic data of some cities in the State of São Paulo and results of controlled perforation testing done in field, in some cities of the State of São Paulo, it presents a model of timber decay in contact with the ground, identifying which cities are more aggressive or less aggressive to the wood in these conditions, proposing the simplification of this model, facilitating its use in the forecast of the timber service life in contact with the ground, predicting the degree of deterioration in them. The proposed model proved to be sufficiently adequate giving a good forecast of the pole deterioration in several regions of the State.
