Description

【発明の詳細な説明】 本発明は、水中又は水没されるケーブルや高湿度で冠水
される可能性のある雰囲気中で使用される外層感知層付
きケーブルに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cable with an outer sensing layer used in a cable that is submerged or submerged in water or in an atmosphere with high humidity and the possibility of being submerged.

体にダメージを与え、導体の伝送関係が異常°となった
ときに初めて検知されており、それ故、ケーブルのみな
らず、システム全体に致命的損害を引起す原因となって
いた。In the past, injuries that occurred after cable installation were only detected when the insulation was damaged and the transmission relationships of the conductors became abnormal. This was the cause of physical damage.
