摘要： Provided is an electrical conducting wire in which eddy current loss is effectively suppressed, mechanical strength is excellent, and electrical conductivity is also excellent while aluminum strands that are not coated with insulating resin are used as strands constituting a split conductor.
An electrical conducting wire, including: a split conductor composed of multiple aluminum strands arranged in parallel to each other or multiple aluminum strands twisted into a helix, wherein each of the strands contains 0.01 to 0.4 mass % of Fe, 0.3 to 0.5 mass % of Cu, 0.04 to 0.3 mass % of Mg, 0.02 to 0.3 mass % of Si, and 0.001 to 0.01 mass % of Ti and V in total, with the balance being Al and inevitable impurities; and wherein each of the strands is not coated with an insulating resin.-
