Underwater Splicing Of SD Coaxial Cable- FY78 Progress
Abstract:
Splicing of SD List 1 coaxial cable on the seafloor has been demonstrated to be feasible using a greasegel filled coaxial splice. Experimental electrical models fabricated for underwater mating have been operated successfully at 6,000 VDC and 5,000 psig ambient pressure with leakage currents less than 1 microa. Impedance mismatches of the electrical models were about 0.4. The search for a compatible dielectric grease for use with the SD cable splice identified a gelling agent Cab-O-Sil which can be used to gel liquids to a grease-like consistency. Castor oil, available in liquid form only, has some unique properties desirable for SD cable splicing applications.
