せた複合ケーブルに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite cable that combines a superconducting cable or cryogenic cable capable of transmitting large amounts of power and an optical fiber capable of transmitting a large amount of information over extremely thin fibers. It is something.

である。As a large-capacity power transmission line, cryogenic cables are made of high-purity copper or aluminum, which has a much lower electrical resistance at extremely low temperatures than at room temperature, and is made of high-purity copper or aluminum as a conductor using liquefied gas such as nitrogen or hydrogen. Superconducting cables are cables that are cooled to 100 to 500"K. Superconducting cables utilize the superconducting phenomenon of metals such as titanium T1, niobium Nb, and vanadium V when their electrical resistance is OK below the critical temperature. All of them utilize the characteristics of low resistance or zero resistance at low temperatures to achieve revolutionary large-capacity power transmission.

い。However, in the low-temperature range of such cables, ordinary organic insulators cannot be used because they become brittle or shrink, causing microbending loss in the optical fibers, so conventional organic insulators, which have been considered preferable in normal cases, cannot be used. Even if an attempt is made to use silicon-coated optical fibers in combination, the original characteristics of the optical fiber cable cannot be exhibited, and in the end, a practical composite cable cannot be obtained.

This is an optical fiber cable provided with a metal pipe 4 such as aluminum or copper, which is combined with the cables shown in FIGS. 2 and 4 below. FIG. 2 shows an example of an optical fiber composite superconducting cable, in which a copper conductor 11 is provided in the center, an internal liquefied nitrogen or helium passage 12 is provided around it, and an outer metal pipe 13 is provided with a copper conductor 11 as shown in FIG. Optical fiber cables 14 as shown in FIG. 1 and intervening materials 15 made of nylon are alternately arranged, and a metal pipe 17 is provided on the outside thereof.

By placing the metal-coated fiber in the vacuum chamber 16, deterioration of the metal coating the fiber can be prevented. On the outside of the metal pipe 17, there is a reflector 18, an external liquid nitrogen or helium channel 19, a metal pipe 20. A cable is constructed by sequentially providing cable sheaths 21 such as PVC.

An optical fiber cable 14 as shown in FIG. 1 is arranged within the twisting gap of the three cores, and the cable core maintains a large refrigerant passage 26 throughout, thereby creating an internal pressure case (electromagnetic shielding). 27, the thermal insulating layer 28 and the external protective case 29 are sequentially superposed to form a cable.
