法に関する。DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD OF THE INVENTION The present invention relates to a method for removing a coating from an insulated wire conductor made by twisting together a plurality of insulated wires each having a thermoplastic resin insulating layer provided on the outer periphery of the wire.
［発明の技術的背景］
近年、電力需要の増大に伴い、電カケープルの導体は大
サイズ化する傾向にある。[Technical Background of the Invention] In recent years, as the demand for electric power increases, the size of the conductor of power cables tends to increase.
このような人サイズ導体においては、交流実効抵抗の低
減が要求されており、その対策として表皮効果、近接効
果の低減のため素線導体外周に熱可塑性樹脂絶縁層を設
け、これを複数条撚合せた素線絶縁導体が開発されてい
る。In such human-sized conductors, it is required to reduce the effective AC resistance, and as a countermeasure to this, a thermoplastic resin insulating layer is provided around the outer periphery of the strand conductor to reduce the skin effect and proximity effect, and this is multi-stranded. Combined strand insulated conductors have been developed.
このような素線絶縁導体どうしを、例えば接続スリーブ
を用いて圧縮接続するためには、上記の熱可塑性樹脂絶
縁層を除去して素線相互間に導電性を持たせる必要があ
る。In order to compressively connect such wire insulated conductors using, for example, a connection sleeve, it is necessary to remove the thermoplastic resin insulating layer to provide conductivity between the wires.
従来、このような熱可塑性樹脂絶縁層を除去する方法と
しては、例えば端部の各素線の絶縁層を紙やすりにより
１本ずつ除去する方法や、導体端部をアルカリ液に浸漬
して絶縁層を溶出させた後洗浄、乾燥する方法が知られ
ている。Conventionally, methods for removing such a thermoplastic resin insulating layer include, for example, removing the insulating layer of each strand at the end one by one using sandpaper, or immersing the conductor end in an alkaline solution to remove the insulation. A method is known in which the layer is washed and dried after being eluted.
［背景技術の問題点］
しかしながら、前者の方法では素線の１本ずつについて
絶縁層の剥離を行なうため作業性が悪く、また後者にお
いては素線の撚合せ間隙に浸透したアルカリ液が水洗で
十分に除去されないで残存し易く、素線の撚合せの長さ

しない部分まで浸蝕させ−でしまう欠点があり、さらに
アルカリ液を用いるために取扱い（こも注意を要すると
いう難点があった。[Problems with the background technology] However, in the former method, the insulating layer is peeled off from each wire one by one, resulting in poor workability, and in the latter method, the alkaline solution that has penetrated into the gaps between the twisted wires cannot be washed with water. There is a disadvantage that the alkaline solution tends to remain without being sufficiently removed, and that the alkaline solution can penetrate in the length direction of the twisted wires, corroding parts of the insulating layer that do not need to be removed. Therefore, it had the disadvantage of requiring careful handling.
