    • There is disclosed an insulated wire, having, on a conductor, an insulating coating including at least three layers, made up of an underlayer formed by applying and baking a polyamine-imide-series resin coating material, containing 0.05 to 1.0 parts by weight of a trialkylamine, and/or 5 to 20 parts by weight of an alkoxylated melamine resin, per 100 parts by weight of a polyamide-imide-series resin, an intermediate layer formed by applying and baking a polyimide-series resin coating material, and an overlayer formed by applying and baking a self-lubricating-type polyamide-imide-series resin coating material. According to the insulated wire, an insulating coating can be prevented from being damaged at the time of the working of a coil under severe conditions, even when the insulating coating is thin.
    • 公开了一种绝缘电线,其在导体上具有包括至少三层的绝缘涂层,所述绝缘涂层由通过涂布和烘烤多胺 - 酰亚胺系树脂涂料而形成的底层构成,所述多胺 - 酰亚胺系树脂涂料含有0.05〜1.0重量份 三烷基胺,和/或5〜20重量份的烷氧基化三聚氰胺树脂,相对于100重量份的聚酰胺 - 酰亚胺系树脂,通过涂布和烘烤聚酰亚胺系树脂涂料而形成的中间层, 通过涂布和烘烤自润滑型聚酰胺 - 酰亚胺系树脂涂料形成的覆层。 根据绝缘电线,即使在绝缘涂层薄的情况下,也可以防止在恶劣条件下在线圈加工时的绝缘层损坏。
