【発明の詳細な説明】
本発明はケーブル導体の製造方法に係り、特に
撚線導体の各素線表面に酸化被膜を形成するに適
した素線絶縁導体の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a cable conductor, and more particularly to a method for manufacturing a stranded insulated conductor suitable for forming an oxide film on the surface of each strand of a stranded conductor.
近年、電力需要の増大とともに、電力ケーブル
の導体は大サイズ化する傾向にある。このような
大サイズ導体においては、いわゆる表皮効果の低
減をはかるために素線絶縁を施すことが行なわれ
ており、その一方法として素線の表面を酸化処理
して絶縁被膜を形成することが行なわれている。 In recent years, as the demand for electric power increases, the conductors of power cables tend to become larger in size. In such large-sized conductors, wire insulation is applied to reduce the so-called skin effect, and one method is to oxidize the surface of the wire to form an insulating film. It is being done.
従来、この素線表面の絶縁被膜形成法には、例
えば撚線導体を構成する素線１本ずつを酸化処理
液中に浸漬させて素線表面に酸化被膜を形成させ
る方法やすでに素線を撚合わせた導体を酸化処理
液中に浸漬させて素線絶縁を施す方法等が知られ
ている。 Conventionally, methods for forming an insulating film on the surface of the strands include, for example, immersing each strand of the strands constituting the stranded conductor in an oxidation treatment solution to form an oxide film on the surface of the strands, or a method in which the strands are already coated. A method is known in which wire insulation is applied by immersing twisted conductors in an oxidizing solution.
しかし上記方法において、前者では表面に酸化
被膜が形成された素線を撚合わせるために、撚合
わせ時に素線表面の酸化被膜が剥離するという難
点があり、又後者では撚線導体を酸化処理液中に
浸漬しても導体表面は酸化されるが、素線の密の
状態で撚合わされているために導体内の素線間に
までは酸化処理液が浸透しにくく、導体内の素線
は酸化されないという難点があつた。 However, in the above method, the former method involves twisting wires with an oxide film formed on their surfaces, so the oxide film on the surface of the wires peels off during the twisting process. The surface of the conductor will be oxidized even if it is immersed in the conductor, but because the wires are tightly twisted together, it is difficult for the oxidizing solution to penetrate between the wires inside the conductor, and the wires inside the conductor are The problem was that it was not oxidized.
本発明は、かかる従来の欠点を解消すべくなさ
れたもので、撚線導体の各素線表面に確実に酸化
被膜を形成させる素線絶縁導体の製造方法を提供
するものである。 The present invention has been made in order to eliminate such conventional drawbacks, and provides a method for manufacturing a stranded insulated conductor that reliably forms an oxide film on the surface of each strand of a stranded conductor.

180g/) and one segment of a six-part compressed copper conductor with a conductor cross-sectional area of 2000mm 2 was passed through the conductor at a linear speed of 1m/min to perform surface oxidation treatment. During this time, ultrasonic waves were emitted into the processing liquid from an ultrasonic vibrator (200 W, 28 kHz), and a vibrating rod that vibrated at 400 cycles per second was brought into contact with the segment to excite it.
