本発明は自己潤滑性に優れた絶縁電線に関するものであ

り性に代表される潤滑性は、このダメージを解消せしめ
る上において極めて重要な特性である。These damages are caused by, for example, streamlining the coil processing process, automation and speeding up by introducing high-speed automatic winding machines, and improvements in the space factor by downsizing and improving the performance of the equipment itself. Such an increase in speed and an improvement in the space factor are very strict conditions for the enamelled wire used. In other words, as the speed increases, the amount of wear increases as the frictional force between the wire and the wire increases, and in some cases, the insulation layer is destroyed, which significantly impedes the electrical properties of the wire. . Therefore, lubricity, represented by slipperiness, is an extremely important characteristic of enameled wire in eliminating this damage.

産性の向上は期侍出来難いもので、ちった。In order to improve this lubricity, conventional methods have been used to coat the surface of the insulating layer with lubricating oil or mother rough-in, or to overcoat with a polyamide resin or the like having lubricity. A method has also been proposed in which a lubricating component such as polyethylene is added to the resin forming the insulating layer. However, even if these methods were implemented, they would not be able to follow the above-mentioned severe coil processing process, and it would be difficult to improve productivity.

である。(Means for Solving the Problems) The present invention provides 0.1 parts of Monta/acid wax per 100 parts by weight of thermosetting resin on a conductor (directly or via another insulating layer).
~7.0 parts by weight and 0.1 to 7.0 parts by weight of an oxidative deterioration inhibitor are added and dissolved in a bath agent to form a lubricating and insulating layer by applying and baking a resin paint. It is something.

れし、外観を阻害するためである。The reason for limiting the blending amount of Montan acid wax to 0.1 to 7.0 parts by weight per 100 parts by weight of the thermosetting resin as described above is that if it is less than 0.1 part by weight, the formed insulation This is because it is difficult to impart lubricity to the layer, and when more than 7.0 parts by weight is added, the surface of the resulting insulating layer becomes rough, impairing its appearance.

しく悪化するためである。The blending amount of these hindered phenolic oxidative deterioration inhibitors is O11 to 7 per 100 parts by weight of the total thermosetting resin.
．． The reason why it is limited to 0 parts by weight is that if the amount is less than 0.1 parts by weight, the resulting insulating film will have poor lubricity, and if it is added in large quantities exceeding 7.0 parts by weight, the appearance of the resulting insulating film will deteriorate significantly.
