Avaliação dos diferentes tipos de conectores em conexões de condutores elétricos isolados

Abstract

The connection between isolated conductors can be performed in different ways, generating different impacts on the performance of the connected elements. One way is to use electrical connectors, manufactured by established standards. This use is common in electrical installations, mainly due to the simplified installation methods, which can be done manually or with few tools. The methods, when executed improperly, end up affecting the connection quality of the connectors in the conductors, and even the rupture of the connection. A bad connection has the potential to change the electrical parameters of the circuit in which it is present, changing the resistance value and, consequently, the current flowing through the circuit. This can lead to a voltage drop at the ends of the circuit and power dissipation at the connection point. In cases of rupture, parts of the conductors are exposed, representing a risk both for the safety of the installation and for people nearby. They can also generate current leaks that increase energy consumption, de-energize the affected circuit, and cause irreversible damage. This work aims to evaluate the impact of five models of electrical connectors used to join insulated conductors, concluding that, when used correctly, they do not affect the conductors, they present a risk of connection failures. This can result in critical safety points, such as dangerous disconnections in electrical installations, highlighting the need to choose care with the types of connectors to avoid accidents and reduce impacts on insulated conductors.
