【考案の詳細な説明】
本考案は光による信号伝送と電力輸送とが同時
に行える複合伝送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 transmission cable that can simultaneously perform optical signal transmission and power transmission.
電力分野における通信回線では、マイクロウエ
ーブの割当に制限があるため、この種回線の高い
需要にこたえるべく、有線による信号伝送の実施
が着目されている。 In communication lines in the electric power field, there is a limit to the allocation of microwaves, so in order to meet the high demand for this type of line, attention is being focused on implementing signal transmission by wire.

た。 However, optical transmission lines that are mainly composed of optical fibers are fragile and require a considerable amount of sheathing to obtain sufficient strength. However, there are also problems in that the structure of the power cable must be significantly modified, and the strength of the optical transmission line is too low compared to the power cable, making it impractical. Was.
本考案は上記の問題点に対処すべくなされたも

(Optical fiber) 8 is housed together with insulating oil, that is, an impregnating medium 9, and is in an internal condition, and a circulation gap is set around the optical transmission line 8 in the protective tube 7, allowing the impregnating medium 9 to freely flow. has been done.

An optical transmission line is installed inside the protective tube 7.
以上に説明した通り、本考案では電力ケーブル

はもちろん、この際の信号伝送は電磁的な誘導障
害を受けることのない光伝送線８によつて行なわ
れるから、単一のケーブルによる上記の複合伝送
が問題なく実施できるのである。 As explained above, in the present invention, the protective tube 7 for supplying the impregnating medium is included in the power cable 1.
The optical transmission line 8 is installed inside the protective tube 7, leaving a gap for the impregnation medium 9 to flow therein.
Of course, power transmission via the power cable 1 and signal transmission (communication using optical signals) via the optical transmission line 8 can be performed, but the signal transmission at this time can also be carried out via the optical transmission line 8, which is not subject to electromagnetic induction interference. Therefore, the above-mentioned composite transmission using a single cable can be carried out without any problems.
しかも、光伝送線８は含浸媒体９の流通性を阻
害しない状態で保護管７内にあるから、この光伝
送線８を収納するための収納空間を電力ケーブル

しに当該複合伝送ケーブルが実現できるように
る。 Furthermore, since the optical transmission line 8 is located within the protective tube 7 without interfering with the flow of the impregnated medium 9, there is no need to provide a separate storage space within the power cable 1 to accommodate the optical transmission line 8. In addition, the optical transmission line 8
However, it is also possible to store the cable as it is in the tube 7 without applying an excessive coating, so if it is a conventional cable with such a tube body, it is not necessary to increase the diameter of the cable or modify the internal structure. This makes it possible to realize the composite transmission cable without having to do so.

ブル製造が行えるようになる。 Furthermore, the optical transmission line 8 inside the protection tube 7 for impregnation supply
The impregnated medium 9 always provides a thermally stable signal transmission state, and the impregnated medium 9 also provides a buffering protective effect. The impregnation medium 9 protects the optical transmission line 8 from external loads and impact forces, preventing large internal distortions, breaks, deterioration and changes in signal characteristics, etc.
Since the cable can be handled while housed in the protection tube 7, mechanical strength problems do not occur at this time either, and the cable can be manufactured without difficulty.
