Submarine Power Cables

Since shortly after the first submarine telegraph cable installations in the early 1800´s, underwater power cables have been implanted and used. Initial acceptance and use of such cables was slow, however, and only accellerated in the past half-century with the replacement of natural rubber insulations. This paper will look into many of the considerations involved in the installation and utilization of submarine or underwater power cables in the long lengths required in most systems. Some of the design considerations involved, some of the types of cables employed, a survey of some of the electrical considerations involved, the dynamics and mechanics of installation will also be discussed. Some thoughts on the future of submarine power cables will be presented.
