Cables 



The primary function of a pressure proof 

 harness assembly is to provide an electrical 

 interconnection point from the electrical hull 

 penetrator to the outboard electrical/elec- 

 tronic component. A harness assembly is a 

 pressure proof cable with connectors wired 

 and sealed to each end (Fig. 7.29). The har- 

 ness is used outboard of the pressure hull 



and usually runs from the hull's electrical 

 penetrator or outboard distribution box to an 

 outboard electrical component. Many types 

 of harness assemblies can be considered and 

 have actually been used on submersibles 

 (Fig. 7.30). However, the majority of those 

 used to date employ rubber jacketed cables. 

 Metal-sheathed, mineral-insulated cables 

 have been used on a few European vehicles, 

 but almost all U.S. designs have made use of 

 conventional neoprene jacketed cables. 



Another output of the DOT program is the 

 Handbook of Electric Cable Technology for 

 Deep Ocean Application (44), a guide pre- 

 pared for deep submergence designers, engi- 

 neers and operating personnel. The Hand- 

 book is a compilation of engineering criteria 

 obtained from literature surveys, experimen- 

 tal investigations and consultation with 

 manufacturers, and provides detailed discus- 

 sions of material selection and construction 

 requirements for reliable deep-ocean cables. 

 Additionally, a glossary and a varied collec-
