Simulation of the operation of a high-temperature conductor made from a newly developed AlAgMo alloy

Recent research in the field of power systems focuses on the development of new conductor materials that will enable increased transmission capacity of currently used power lines. This need arises from the often limited ability to continuously and reliably electricity transmission. Although many technical solutions for these conductors are available on the market, they exhibit several drawbacks, ranging from their high cost, various operational difficulties and complex installation techniques to the risk of monopolistic practices due to the lack of access to multiple competitive suppliers. As part of this research, a new aluminium-based alloy with the addition of silver and molybdenum was developed using a laboratory-scale continuous casting process and subsequently subjected to wire drawing. This alloy is intended for use as a conductive strand in the group of HTLS (High-Temperature Low-Sag) conductors. The article presents theoretical calculations illustrating the operation of a high-temperature conductor made from the newly developed AlAgMo alloy, showing the sag range and current-carrying capacity in comparison to a conventional conductor and a high-temperature conductor with AlZr alloy wires.
