Abstract : The mechanical properties of shielded and unshielded submarine cables (MIL-C-915/8E) were investigated to determine the effect of shielding on cable life, performance and reliability. Ten cables, five shielded and five unshielded, were selected for laboratory evaluation. A mission profile was developed to establish the mechanical stress limits cables must endure in service and a test sequence designed to measure tensile strength, flexural abrasion endurance, crush resistance, creep under static tension and performance in a hull stuffing tube. The results of this program showed the following: DSS-2 cable does not have adequate tensile strength and should have a strength member added. DSS-3 and larger cables have adequate tensile strength with and without the shield; Unshielded DSS-3 type cables does not perform satisfactorily in hull stuffing tubes; Shielding is not required to meet Mission Profile specifications for cable crush or flexural abrasion resistance; Construction parameters other than shielding can significantly affect mechanical performance of cable; Unshielded cable construction can result in increased reliability since it permits a thicker single jacket construction; and Unshielded cable construction can reduce the cost of cable by 8% to 20%.
