Análisis de la influencia del torque de apriete en la eficacia del conector ranura paralela perno central en los conductores eléctricos 6 y 4/0 AWG comercializado en Ecuador

Abstract

This study conducted an in-depth analysis of the influence exerted by tightening torque on the efficiency of parallel groove connectors with central bolts, used in 6 and 4/0 AWG electrical conductors marketed in Ecuador. The primary objective was to determine how variations in torque directly impact the quality of electrical connections, focusing on key parameters such as contact resistance and mechanical stability. An experimental approach was employed, involving laboratory tests to assess the effects of different torque values on connector efficiency. These tests included simulations replicating real operating conditions, such as vibrations and thermal fluctuations, to collect precise data and establish an optimal tightening range. The findings revealed that torque below the recommended levels significantly increased contact resistance and led to mechanical failures, while excessive torque caused deformations on contact surfaces, reducing their effectiveness. In contrast, the optimal torque range maximized mechanical stability and minimized energy losses. In conclusion, this study underscores the importance of applying proper torque to ensure safe and efficient electrical connections, significantly contributing to the improvement of installation practices in local electrical systems.
