Projecto de uma rede de distribuição de energia eléctrica para o Bairro de Macandza, Distrito de Marracuene

Abstract

This paper details the project for the expansion of the medium voltage (MV) and low voltage (LV) electrical power distribution network for the Macandza Neighborhood, located in the Marracuene district, Mozambique. Motivated by repeated complaints from residents regarding the lack of electricity supply and aiming to meet the needs of potential future residents in the neighboring Tinguana 1 and 2 and Nandza neighborhoods, this proposal considers the electrification of 200 households. Through calculations based on the Regulation for the Safety of Electrical Energy Utilization Installations (RSIUEE), a predictable power of 1017 kVA was estimated, leading to the dimensioning of a 6x200 kVA transformer’s substations, to be supplied by a 12.5 km long 33 kV (MV) line derived from the existing network. The MV line will use 150 mm² Mulberry (AAAC) conductor, supported by 209 poles. The LV network will be implemented with 4x50 mm² aluminum bundled conductor (ABC), with an extension of 2720 m and supported by 68 poles. This project aims to solve the lack of electricity in Macandza and prepare the infrastructure for the future development of the region.
