    • PROBLEM TO BE SOLVED: To provide a communication cable capable of avoiding bad effect on a signal transmitted by a pair of twisted insulated conductors, by preventing the cross talk between the pair of twisted insulated conductors in the conduction cable.
      SOLUTION: The communication cable is composed of an elongated cable jacket having an inside cavity and a plurality of paired twisted insulated conductors in which respective conductors are insulated with a polymer layers and which are arranged in the inner cavity of the cable jacket. Respective paired twisted insulated conductors are constructed into a pair spiral twisted with a first rotative direction, and respective twisted pair of conductors forms into a bundle of spiral twisted with a second rotative direction which is reverse to the first rotative direction. By the above arrangement, an allowable cross talk prevention and attenuation property can be provided even by using a foamed insulation body having a property shown not allowable to use when the pair is bundled and twisted only in one twisting direction.

    • 要解决的问题:通过防止导电电缆中的一对扭绞绝缘导体之间的串扰,提供能够避免由一对扭绞绝缘导体传输的信号的不良影响的通信电缆。 解决方案:通信电缆由具有内腔和多个成对扭绞绝缘导体的细长电缆护套组成,其中各导体与聚合物层绝缘并且布置在电缆护套的内腔中。 各配对扭绞绝缘导体被构造成具有第一旋转方向的螺旋扭绞对,并且相应的双绞线导体形成为与第一旋转方向相反的第二旋转方向的螺旋扭绞束。 通过上述结构,即使使用具有不可允许使用的性质的发泡绝缘体,也可以提供允许的串扰防止和衰减性,该发泡绝缘体仅在一个扭转方向上被捆扎和扭曲时才能使用。 版权所有(C)2005,JPO&NCIPI
