INSULATED WIRE FOR HIGH-TEMPERATURE ENVIRONMENT

摘要

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 highvacuum environment or in a high-temperature environment. This insulated electrical wire has a conductor core made of a base material, an anodic oxide layer, and an oxide insulating layer. The base material 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 is formed on the surface layer. The oxide insulating layer is formed on the anodic oxide layer by a sol-gel method or an organic acid salt pyrolytic method. This insulated electrical wire exhibits good heat resistance and good insulation strength, as well as excellent flexibility, and does not provide any gas adsorption source.
