Rheological Inactivity of AIMgSi Conductors (AAAC) in Trend of Negative Stress Gradients

The authors of this paper present the research results of low temperature creep of AlMgSi (6101) wires and AAAC - All Aluminium Alloy Conductor. The conductor is made from AlMgSi wires (diameter 2.99 mm). Based on theoretical analysis it was proved that creep of an overhead conductors depends on the relation between stress and temperature of conductor and the span geometry. Thus the objective of the paper is to determine the wire and conductor creep under the conditions of stress drop. On the basis of the research it has been observed that the creep of both the AAAC conductor and the AlMgSi wires temporarily stopped.
