Abstract

Abstract

This paper presents data about the potential use of wood from Corymbia citriodora, Eucalyptus cloeziana and Eucalyptus dunnii species as crossarm used on utility poles. Results presents the productive process efficiency of each specie, with mechanical properties analysis, a study of Chromated Copper Arsenate (CCA) preservative penetration in the wood and economic and functional considerations about wood as material. The Corymbia citriodora presented the highest performance, with a yield of 75%, followed by Eucalyptus cloeziana, with 42%. The specie Eucalyptus dunnii was disqualified due to a very low yield, of only 7%.The bending strength test revealed that Corymbia citriodora and Eucalyptus cloeziana attended the resistance requirements of the Brazilian Standard NBR 8458/1984. There was total penetration of CCA in the sapwood of the specie Corymbia citriodora which, with its heartwood natural resistance and production efficiency, classifies this species as the best among the ones studied. Based on the results, it is possible to conclude that the use of wood as material to crossarms in Brazil is viable, and less harmful to the environment, since it is a natural and renewable resource.

Keywords: Treated wood; crossarms; bending strength.
