绝缘电线、同轴电缆及多芯电缆
摘要：
提供一种绝缘电线、同轴电缆及多芯电缆，其可以减小绝缘体的介电常数，在细径下得到良好的电气特性，而不会导致耐电压性降低及强度降低。同轴电缆（11）的中心导体（12）由具有沿长度方向连续的空隙部（14）的绝缘体（13）覆盖，在绝缘体（13）的外周配置外部导体（15），空隙部（14）形成为剖面圆形或椭圆形状，在绝缘体（13）中均等地配置6至8个空隙部（14），在与同轴电缆（11）的长度方向垂直的剖面上，在将空隙部（14）的面积相对于所有空隙部（14）的面积和绝缘体（13）的面积之和的比例作为空隙率时，使得所有空隙部（14）总计的空隙率大于或等于18%而小于或等于35%。
摘要（英）：

Provided are an insulated wire, a coaxial cable, and a multicore cable that are insulated with insulators having a low dielectric constant, are small in diameter and can obtain good electrical characteristics with no decrease in withstand voltage or strength. Core conductors (12) of a coaxial cable (11) are enclosed by an insulator (13) having longitudinally continuous apertures (14). Outer conductors (15) are disposed along the outer circumference of the insulator (13). The apertures (14) have a cross-sectional circular shape or elliptical sectional shape. There are 6 to 8 apertures (14) which are evenly arranged in the insulator (13). In a cross section perpendicular to the length direction of the coaxial cable (11), when the aperture ratio is defined as the ratio of the area of the apertures (14) to the sum of the total area of the apertures (14) and the area of the insulator (13), the aperture ratio for all apertures (14) combined is 18% to 35%.
