Cable design and manufacture for the transatlantic submarine cable system

The transatlantic cable project required that two repeatered cables be laid in the deep water crossing between Newfoundland and Scotland, and one across the shallower waters of Cabot Strait. The same structure was adopted for the cables laid in the two locations. The paper discusses the considerations leading to the design of the cable and describes the method of manufacture, the means and equipment for control of cable quality, the process and final inspection procedures, the electrical characteristics of the cable and factors relating to mechanical and electrical reliability of the final product.
