A Study of The Artificial Ageing on The Low Temperature Creep of AlMgSi (AA6201) Wires

Abstract

The study topic focuses on testing low-temperature rheological processes in wires made of AlMgSi conductor alloys. The need for research on the creep process in AlMgSi alloy wires results form the fact that they are used in the construction of selfsupporting overhead power lines. One of the main operational hazards for overhead conductors are rheological processes that result in permanent length increases in conductors hanging in spans (creep process) Due to the fact that these processes take place in a temperature range below 100°C, they do not result in immediate destruction of the material, as is the case in high temperature processes; however, they are a cause of emergency line disconnections. The study, which has an experimental character, identifies opportunities to control AlMgSi wires creep.
