Shared trench for burying cables in the conversion of overhead to underground networks
2022 IEEE Conference on Technologies for Sustainability (SusTech)(2022)
Abstract
Presented as a strong trend around the world, the burial of electricity networks aims to mitigate conflicts with the physical environment, generating positive aspects in the use of public space, in the aesthetics of the urban environment, in addition to contributing to the safety of citizens. Such action is already implemented in several countries, having as standard the installation of low voltage cables on sidewalks and medium voltage cables on roadways. However, due to the high number of interferences and the high maintenance and operation costs, as well as the possible negative impacts on the environment and traffic, it is not always feasible to use this process, especially in large urban centers. Thus, this article brings to light the study of a new method of allocation of pipelines for underground electricity distribution grids, based on the premise of sharing trenches between low and medium voltage grids, presenting the innovative constructive methods involved and the direct benefits to society and the environment. This study is part of an R&D project proposed by ENEL Distribuição São Paulo, called "Urban Futurability", which, together with other work fronts, develops a new concept of a pipeline bank.
