Undeterred, the company placed a new order in 1850, but this time the cable was to be sent to a wire rope manufacturer for armouring before laying. This order was four times [14] as large as the 1849 order since the new cable was to have four gutta-percha insulated cores. This cable was a success, and became the first working oceanic submarine ...
The fleet angle compensator (FAC) is driven by the movement of the wire rope as it goes through the crossover sections of the drum. As the rope winds or unwinds, the FAC shaft automatically oscillates slowly, allowing its sheave to slide back and forth across the shaft to maintain an optimum fleet angle and guide the rope smoothly onto the drum.

Wire was drawn in England from the medieval period. The wire was used to make wool cards and pins, manufactured goods whose import was prohibited by Edward IV in 1463. [5] The first wire mill in Great Britain was established at Tintern in about 1568 by the founders of the Company of Mineral and Battery Works, who had a monopoly on this. [6]
