  • High strength cable usable undersea
    Patent number: 4345112
    Abstract: This invention relates to a high strength cable to electrically and mechaally connect a vessel or a base on the sea with submarine instruments. Such a cable is required to transfer a signal or electric power and to positively transfer to a tension member in the cable a drawing force which is applied to an outer sheath from a capstan when the cable is wound up or drawn out by the capstan. This invention has a feature in that layers 6A, 6B, 6C and 6D of lapping tape having a high friction coefficient such as rubber coated tape are provided between a tension member 7 and an outer sheath 8. This feature prevents a displacement between the tension member 7 and the outer sheath 8.
