The objective of this work was to analyze the interaction between street trees and the high-tension electricity distribution network, while also evaluating the tree species used in the city of Maringá, Paraná State, specifically in the Zona 7 neighborhood. This area was chosen for its local peculiarities, such as the use of large-sized trees and the different types of electricity networks (conventional and compact for high tension, and conventional and isolated for low tension). It was observed that large-sized tree species prevail, such as Caesalpinia peltophoroides and Tipuana tipu, which represent 32.92 and 30.79% of total planted trees, respectively. The final result showed a reduction in impact caused by trees on the electrical network, as electricity supply quality indicators improved by up to 80%. Network maintenance costs were reduced significantly, and tree quality, especially from the reduction in pruning, showed considerable improvements, confirming the efficacy of the protected compact network when compared to the others.
