Armored submarine power cable

摘要

Armored submarine power cables are designed for laying in waters with varying depths. The cable has an armor which is heavy and strong (steel wires) in shallow water sections. In very deep waters the weight of steel armor is prohibitive so that in these sections the armor is made of synthetic light weight material. The transitions between the two types of armor are made physically concentrated but flexible enough to prevent sharp bends of the cable core as it passes cable laying machinery. The armor joint may be displaced from cable core joints and substantially effectively transfers all longitudinal strain in the cable.
