Abstract

Steel-aluminum wires, despite their common use, show insufficient operational properties for current needs. Their main disadvantages are high mass and maximum operating temperature limit that guarantees the stability of mechanical properties at 80 °C, which more and more often proves to be insufficient. Current trends in the overhead electrical power engineering in the area of wire materials, include e.g. the improvement of aluminum alloys for electrical purposes, development of composite cores in place of steel in bimetallic conductors and overall improvement of mechanical, electrical and operational properties of the wires. Alloying pure aluminum with other elements results in an inevitable decrease of its electrical conductivity, but at the same time it creates the possibility for the mechanical and operating properties improvement. The article presents the research results on drawing process for the new aluminum based alloys with the addition of zirconium, silver and molybdenum. Technical aluminum grade was used as a reference material. This paper presents an analysis of the properties of the produced wires dedicated for electrical applications. Wires were obtained in a laboratory continuous casting process with various process parameters.
