Insulated wire

Abstract

An insulated electrical wire is suitable for use as a distribution wire, a wire for winding coils, and for other electrical purposes. The wire can be used in a high-vacuum environment or in a high-temperature environment. This insulated electrical wire has a conductor core made of a base material (1), an anodic oxide layer (2), and an oxide insulating layer (3). The base material (1) forms a conductor core and has a surface cover of either an aluminum layer or an aluminum alloy layer at least on its outer surface. The anodic oxide layer (2) is formed on the surface layer. The oxide insulating layer (3) is formed on the anodic oxide layer by a sol-gel method or an organic acid salt pyrolytic method. This insulated electrical wire has a good heat resistance and a good insulating strength as well as excellent flexibility, and does not provide any gas adsorption source.
