熱劣化を防止することが必要となってきている。(Prior Art) Coaxial cables are increasingly being used as power supplies for computers and electronic devices to prevent external noise or voltage drops. Moreover, in recent years, the wiring space, weight, and volume of this type of coaxial cable for wiring in aircraft, submarines, etc. have become problematic, and there is a demand for a light coaxial cable with excellent flexibility. In particular, for aircraft applications, the inner and outer conductors must be designed at the limit of the operating current due to weight considerations, and for this purpose, the cross-sectional areas of the inner and outer conductors must be approximated to prevent heat generation and deterioration due to imbalance between the inner and outer conductors. It has become necessary.

導体断面積を近似させるにも限界があった。Conventional coaxial cables had relatively large conductor cross-sectional areas relative to their current capacity, and could be constructed by twisting strands of normal diameter, since the installation location and weight were not so important. However, as mentioned above, in order to approximate the cross-sectional areas of the inner and outer conductors, the outer conductor has been constructed with two or three layers of braid, or with a large number of strands wound horizontally. However, the former has extremely poor workability, while the latter makes it difficult to evenly horizontally wind a large number of strands in the longitudinal direction, and since both have large strand diameters, the cross-sectional areas of the inner and outer conductors are approximated. There were also limits.
