Title
(EN) INSULATED ELECTRIC WIRE
(FR) FIL ÉLECTRIQUE ISOLÉ
(JA) 絶縁電線
Abstract
(EN)
An insulated electric wire having a conductor and an air-bubble-containing insulation layer that includes a heat-curable resin, the insulation layer directly or indirectly covering the outer peripheral surface of the conductor, wherein the air bubbles in the air-bubble-containing insulation layer include flat air bubbles such that the flatness of the air bubbles (length in the lateral direction of the air bubble cross-sectional shape/length in the longitudinal direction of the air bubble cross-sectional shape) in a cross section perpendicular to the longitudinal direction of the insulated electric wire is 1.5-5.0, inclusive.
(FR)
L'invention concerne un fil électrique isolé ayant un conducteur et une couche d'isolation contenant des bulles d'air qui comprend une résine thermodurcissable, la couche d'isolation recouvrant directement ou indirectement la surface périphérique externe du conducteur, les bulles d'air dans la couche d'isolation contenant des bulles d'air comprenant des bulles d'air plates de telle sorte que la planéité des bulles d'air (longueur dans la direction latérale de la forme de section transversale de bulle d'air / longueur dans la direction longitudinale de forme de section transversale de bulle d'air) dans une section transversale perpendiculaire à la direction longitudinale du fil électrique isolé est de 1,5 à 5,0 inclus.
(JA)
導体と、該導体の外周面を直接又は間接的に被覆する、熱硬化性樹脂を含む気泡含有絶縁層とを有する絶縁電線であって、前記気泡含有絶縁層中の気泡が、前記絶縁電線の長手方向に垂直な断面における、気泡の扁平率(気泡断面形状の横方向の長さ/気泡断面形状の縦方向の長さ)が1.5以上5.0以下である扁平気泡を含む、絶縁電線。
