INSULATED COVERED ALUMINUM WIRE

摘要

An insulated covered aluminum wire which comprises, on the outer circumference of a conductor, an insulating covering layer that contains a resin having at least a benzene ring and an imide ring, and which is covered by two or more insulating covering layers. The resin which constitutes the innermost insulating covering layer that is in contact with the conductor has a molar ratio of the imide ring content to the benzene ring content of 0.366 or more as determined by formula (1). In addition, the absolute value of the difference of the above-described molar ratio of the imide ring content of the constituent resin between adjacent insulating covering layers is more than 0 but 0.167 or less with respect to any two adjacent insulating covering layers. Total number of moles of imide rings in resin/total number of moles of benzene rings in resin formula (1)
