. Deep ocean power systems. Electric power distribution; Hydroelectric power plants. 10 20 30 40 Distance of Maximum Horizontal Projection (ft) Figure 16. Maximum horizontal projection of mooring leg. Cable Sheaths and Coverings Submarine cables usually have a water-resistant covering over their insulation as added protection. Neoprene or polyethylene may be used for this purpose. Where additional mechanical strength and abrasion resistance is required, the cable covering is wrapped with armor wire of bronze, copper, stainless steel, or galvanized steel. An additional covering is applied to pro- tect the armor from the sea environment. High-strength galvanized steel with polyethylene covering was selected as the armor material. Electrical Properties The use of either three single-conductor cables or a single three- conductor cable is feasible for an underwater power transmission system. The costs involved in deploying three single-conductor cables are greater than those involved in deploying one three-conductor cable. In addition, three single conductors have a higher reactance than one three-conductor cable. Off-the- shelf three-conductor cables with standard conductor wires were considered in the study. 53.
