Harness Design and Manufacture
When designing an underwater cable harness, there are some factors which need to be considered, and we have produced the following list as a guide for customer information:Component considerations:- Electrical requirements- Mechanical considerations- Quality requirements- Reliability- Design redundancy (contact count)- Connector selection (type and form)- Locking requirements- Backpotting requirements- Waterblocking in moldings- Cable specification- Cable jacket material and compatibility with elastomers- Abrasion resistance- Stiffness profile at termination- Connector format (straight or right angle)- Molding format (straight or at an angle)- Clearance allowance for molding and cable routing- Elastomer compatibility (eg oil filled units)- Metalwork selection re: corrosion and cathodic delamination- Surface finish for metalwork as appropriateOperational considerations:- Operating depth profile (not just max. depth)- Tensile loads- Torsional loads- Bending loads- Bend control requirements (to limit bending at termination)- Deployment and recovery loads- Dynamic loading-Flow turbulence effects.
