Redimensionamento da rede de distribuição subterrânea de energia eléctrica de média tensão que interliga os bairros da Coop e Sommerschield, ( de PS13 até SE5) na Cidade de Maputo

Abstract

This work has as its main approach, the improvement of the underground medium medium voltage network in the Coop and Sommerschield neighbourhoods. Since this line operates overloaded and has many outages due to human-caused cable faults. cable defects caused by humans. In view of this we have the solution, and to achieve this the underground network connecting these two neighbourhoods has been re-dimensioned, In particular, the cable from SE05 to PS13 has been re-dimensioned. the solution we used was aluminium cable, with the following characteristics characteristics, LXLPE 1 x 800 mm 2 , 11KV, AL cable, and its protections with the characteristics of the main circuit breaker, SN-800 A, with a breaking capacity of 20KA from SACE, to be installed in PS13. The best possible grid layout has been determined by possible for the grid, changing the route of the current grid in areas where the power cable is under under residences over a stretch of approximately 800 metres, to a public space, such as a a public space, such as pavements and/or verges and streets. By comparative comparative analysis as well as the estimated costs made its implementation is feasible since the project proposes an economical solution for the re-dimensioning of the underground medium voltage network.
