Substituição dos cabos subterrâneos por linha aérea de média tensão de 11 KV que interligam a Subestação de Aeroporto ao PS12 do Bairro Aeroporto a Chamankulo

Abstract

In order to find solutions for the supply of uninterrupted power electricity to its consumers without keeping EDM has been looking for a more effective. In this present work, interpret the implementation of an area line as a solution more viable for the distribution and supply of energy in medium voltage circuits, the aims to describe the constitutional and technical aspects used in creating networks company. In this way, it is necessary to know the advantages and security provided over the overhead network during normal operation, maintenance period and lifetime useful compared to existing underground cables. The development of this work was carried out with the help of manuals obtained during the course and information provided by Electricidade de Moçambique. The proposal to replace the existing underground cables is due to the constant breakdowns along the circuit that suffered from dependency and constant maintenance. However, the new circuit should bring improvements to the network in terms of performance and implementation costs. In turn to design this circuit it was necessary to the electrical sizing that deals with line operating parameters and the mechanical dimensioning that studies the motors developed by the cables and factors atmospheric pressures on the supports. Using the Google Earth online topographic platform it was possible to demonstrate the section that the line travels respecting the safety of people and assets.
