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 grease/gel 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 micro(a). 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.
